Full textAbstract:
Massively multiplayer online games (MMOGs) have become highly popular in the last decade and now attract millions of users from all over the world to play in an evolving virtual world concurrently over the Internet. The high popularity of
MMOGs created a rapidly growing market and this highly dynamic market has forced the game developers to step up competitively. However, MMOG development is a challenging and expensive process. In this study, we have developed a network simulation tool which can be used to model and simulate typical MMOGs that have client-server architectures. The main objective is to provide a simulation environment to MMOG developers that could be used to test, analyze and verify various aspects of the MMOG network architecture. We have also implemented a graphical user interface which allows constructing the simulation model visually. We have demonstrated the use of simulation tool by experimental simulations.

Full textAbstract:
The study investigated the use of Massively Multiplayer Online Games (MMOG) in English and Business classrooms in Higher Education from the context of learners’ performance outcomes, as well as stakeholders’ (learners, administrators, and faculty) perceptions pertaining to their experiences when using an MMOG based curriculum. The findings strongly suggest that MMOGs helped enhance learner performances in statistically significant ways, and provided valuable insights into elements of interest and concerns of stakeholders about MMOG usage in classrooms. Based on these insights, I designed a practitioners’ guide to assist future scholars interested in this curricular approach. This guide provides innovative tips on show how faculty, administrators and institutions may imbibe this cutting-edge technology in easy and affordable ways within classrooms, while dealing with several concerns such stakeholders may have regarding the use of such games. Given the rise in popularity of game based technology and the existing literature on the value of game based education, coupled with a paucity of studies examining applicability and implementation issues in the context of using MMOGs, I hope that this submission will be a valuable contribution to the literature.

Full textAbstract:
Network computer games are played amongst players on different hosts across the Internet. Massively Multiplayer Online Games (MMOG) are network games in which thousands of players participate simultaneously in each instance of the virtual world. Current commercial MMOG use a Client/Server (C/S) architecture in which the server simulates and validates the game, and notifies players about the current game state. While C/S is very popular, it has several limitations: (i) C/S has poor scalability as the server is a bandwidth and processing bottleneck; (ii) all updates must be routed through the server, reducing responsiveness; (iii) players with lower client-to-server delay than their opponents have an unfair advantage as they can respond to game events faster; and (iv) the server is a single point of failure.The Mirrored Server (MS) architecture uses multiple mirrored servers connected via a private network. MS achieves better scalability, responsiveness, fairness, and reliability than C/S; however, as updates are still routed through the mirrored servers the problems are not eliminated. P2P network game architectures allow players to exchange updates directly, maximising scalability, responsiveness, and fairness, while removing the single point of failure. However, P2P games are vulnerable to cheating. Several P2P architectures have been proposed to detect and/or prevent game cheating. Nevertheless, they only address a subset of cheating methods. Further, these solutions require costly distributed validation algorithms that increase game delay and bandwidth, and prevent players with high latency from participating.In this thesis we propose a new cheat classification that reflects the levels in which the cheats occur: game, application, protocol, or infrastructure. We also propose three network game architectures: the Referee Anti-Cheat Scheme (RACS), the Mirrored Referee Anti-Cheat Scheme (MRACS), and the Distributed Referee Anti-Cheat Scheme (DRACS); which maximise game scalability, responsiveness, and fairness, while maintaining cheat detection/prevention equal to that in C/S. Each proposed architecture utilises one or more trusted referees to validate the game simulation - similar to the server in C/S - while allowing players to exchange updates directly - similar to peers in P2P.RACS is a hybrid C/S and P2P architecture that improves C/S by using a referee in the server. RACS allows honest players to exchange updates directly between each other, with a copy sent to the referee for validation. By allowing P2P communication RACS has better responsiveness and fairness than C/S. Further, as the referee is not required to forward updates it has better bandwidth and processing scalability. The RACS protocol could be applied to any existing C/S game. Compared to P2P protocols RACS has lower delay, and allows players with high delay to participate. Like in many P2P architectures, RACS divides time into rounds. We have proposed two efficient solutions to find the optimal round length such that the total system delay is minimised.MRACS combines the RACS and MS architectures. A referee is used at each mirror to validate player updates, while allowing players to exchange updates directly. By using multiple mirrored referees the bandwidth required by each referee, and the player-to mirror delays, are reduced; improving the scalability, responsiveness and fairness of RACS, while removing its single point of failure. Direct communication MRACS improves MS in terms of its responsiveness, fairness, and scalability. To maximise responsiveness, we have defined and solved the Client-to-Mirror Assignment (CMA) problem to assign clients to mirrors such that the total delay is minimised, and no mirror is overloaded. We have proposed two sets of efficient solutions: the optimal J-SA/L-SA and the faster heuristic J-Greedy/L-Greedy to solve CMA.DRACS uses referees distributed to player hosts to minimise the publisher / developer infrastructure, and maximise responsiveness and/or fairness. To prevent colluding players cheating DRACS requires every update to be validated by multiple unaffiliated referees, providing cheat detection / prevention equal to that in C/S. We have formally defined the Referee Selection Problem (RSP) to select a set of referees from the untrusted peers such that responsiveness and/or fairness are maximised, while ensuring the probability of the majority of referees colluding is below a pre-defined threshold. We have proposed two efficient algorithms, SRS-1 and SRS-2, to solve the problem.We have evaluated the performances of RACS, MRACS, and DRACS analytically and using simulations. We have shown analytically that RACS, MRACS and DRACS have cheat detection/prevention equivalent to that in C/S. Our analysis shows that RACS has better scalability and responsiveness than C/S; and that MRACS has better scalability and responsiveness than C/S, RACS, and MS. As there is currently no publicly available traces from MMOG we have constructed artificial and realistic inputs. We have used these inputs on all simulations in this thesis to show the benefits of our proposed architectures and algorithms.

Full textAbstract:
Massively Multiplayer Online Role Playing Games (MMORPGs) are a prominent genre in today's video game industry with the most popular MMORPGs generating billions of dollars in revenue and attracting millions of players. As they have grown, they have become a major target for both technological research and sociological research. In such research, it is nearly impossible to reach the same player scale from any self-made technology or sociological experiments. This greatly limits the amount of control and topics that can be explored. In an effort to make up a lacking or non-existent player-base for custom-made MMORPG research scenarios A.I. agents, impersonating human players, can be used to "bootstrap" the research scenario to reach the necessary massive number of players that define the game genre.
This thesis presents a system that makes its human players and A.I. players indistinguishable while preserving the basic characteristics of a typical MMORPG. To better achieve identical perception of human and A.I. players, our system centers around the collection, sharing, and exchange of information while limiting the means of expression and actions of players. A gameplay scenario built on the Panoptyk engine was constructed to imitate gameplay experienced in major MMORPGs. We conducted a user-study where subjects play through the scenario with a varying number of A.I. players unknown to them. Three versions of the scenario were created to assess how indistinguishable human and A.I. players were and vice versa.
We found, across 24 participants, there were 32% correct identifications, 30% incorrect identifications, and 38% answers of "I don't know". This was broken down into 20% correct identifications, 42% incorrect identifications, and 38% answers of "I don't know" for bot characters and 46% correct identifications, 16% incorrect identifications, and 38% answers of ``I don't know'' for human characters.

Full textAbstract:
This thesis explores how massively multiplayer online games (MMOGs), as an exemplary new media form, disrupt practices associated with more conventional media. These intensely social games exploit the interactivity and networks afforded by new media technologies in ways that generate new challenges for the organisation, control and regulation of media. The involvement of players in constituting these games - through their production of game-play, derivative works and strong social networks that drive the profitability of the games - disrupts some of the key foundations that underlie other publication media.
MMOGs represent a new and hybrid form of media - part publication and part service. As such they sit within a number of sometimes contradictory organising and regulatory regimes. This thesis examines the negotiations and struggles for control between players, developers and publishers as issues of ownership, governance and access arise out of the new configurations.
Using an ethnographic approach to gather information and insights into the practices of players, developers and publishers, this project identifies the characteristics of the distributed production network in this experiential medium. It explores structural components of successful interactive applications and analyses how the advent of player agency and the shift in authorship has meant a shift in control of the text and the relations that surround it. The integration of social networks into the textual environment, and into the business model of the media publishers has meant commerce has become entwined with affect in a new way in this medium.
Publishers have moved into the role of both property managers, of the intellectual property associated with the game content, and community managers. Intellectual property management is usually associated with the reproduction and distribution of finished media products, and this sits uneasily with the performative and mutable form of this medium. Service provision consists of maintaining the game world environment, community management, providing access for players to other players and to the content generated both by the developers and the other players.
Content in an MMOG is identified in this project as both the 'tangible' assets of code and artwork, rules and text, and the 'intangible' or immaterial assets of affective networks. Players are no longer just consumers of media, or even just active interpreters of media. They are co-producing the media as it is developed. This thesis frames that productiveness as unpaid labour, in an attempt to denaturalise the dominant discourse which casts players as consumers.
The regulation of this medium is contentious. Conventional forms of media regulation - such as copyright, or content regulation regimes are inadequate for regulating the hybrid service/publication medium. This thesis explores how the use of contracts as the mechanism which constitutes the formal relations between players, publishers and developers creates challenges to some of the regimes of juridical and political rights held by citizens more generally.
This thesis examines the productive practices of players and how the discourses of intellectual property and the discourses of the consumer are mobilised to erase the significance of those productive contributions. It also shows, using a Foucauldian analysis of the power negotiations, that players employ many counter-strategies to circumvent the more formal legal structures of the publishers. The dialogic relationship between players, developers and publishers is shown to mobilise various discursive constructions of the role of each. The outcome of these ongoing negotiations may well shape future interactive applications and the extent to which their innovative capacities will be available for all stakeholders to develop.

Full textAbstract:
Traditional 2-D contour models, Physical Models, Computer-Aided Architectural Design (CAD), Virtual Reality models, Google SketchUp, and Building Information Modelling (BIM) have all greatly enhanced the design process by enabling designers to visualise buildings and the space within them prior to their construction. A recent development is Massively Multiplayer Online Games (MMOG) such as Second Life (SL). These offer users the opportunity to interact with other participants in real time, and so offer an excellent opportunity to experience the environment, layout and form of virtual buildings. However, the effectiveness of such applications to some extent depends upon how realistic the interactions of those using virtual spaces are in relation to interactions within the real world. This research examines the potential of this technology for enhancing and informing the early stage building design process. Initially, the tools currently used by architects at early stages of the RIBA Plan of Work were evaluated through interviewing architects. Then, the advantages of using MMOG over current tools at early-stage design were evaluated through interviews in SL. A virtual model was developed to examine how realistic the visualisation and interaction between end-users in an MMOG was. This was used to propose and validate guidance to incorporating MMOG into the early stages of the RIBA Plan of Work. It revealed that the virtual model created, the validated guidance and a successful example combining 2D sketches, Google SketchUp and MMOG at early-stage design can be used to guide architects to manage the complex decision making process in a simple, easy, cost-effective way, while effectively engaging both professional and non-professional stakeholders.

The goal of this Thesis is not only a plain description of common characteristics of Massive Multiplayer Online Games (their sorting and conditions on where they run are included), but also their integration to the wider phenomenon -- to cyberspace. Cyberspace reference is present in all recommendations and game specifics. Cyberspace is it`s base ingredient, the authority, to which all those parts are revoking to. And here it comes our second and main goal. The need of integration of players to that virtual world. To seek her desires, her true nature. That maybe done by describing various game devices and methods of connecting users of those devices to the cyberspace, let alone by expanding reader`s horizons to places, not known to her. All that is lead by one effort -- that the person, who will read that Thesis carefully, will be able to answer the question, if players get exactly what they need. And she`ll be able to do that before reading to the end.

Tradicionalmente, utiliza-se um servidor central para prover suporte a MMOGs (massively multiplayer online games, ou jogos online maciçamente multijogador), nos quais o número de participantes é da ordem de dezenas de milhares. Muitos trabalhos foram realizados com o intuito de criar um modelo de suporte completamente descentralizado, par-a-par, para este tipo de aplicação, minimizando o custo de manutenção da sua infraestrutura, mas algumas questões críticas persistem. Exemplos de problemas do modelo de suporte par-a-par são: vulnerabilidade a trapaça, sobrecarga da banda de envio dos pares e dificuldade para manter a consistência da simulação entre os diferentes participantes. Neste trabalho, é proposta a utilização de nodos de baixo custo geograficamente distribuídos, operando como um servidor distribuído de jogo. O modelo de distribuição proposto e alguns trabalhos relacionados também são apresentados. Para tratar o custo de comunicação imposto aos servidores, foi projetado aqui um novo refinamento para a técnica de gerenciamento de interesse, reduzindo significativamente a largura de banda necessária ao jogo. Foram realizadas simulações utilizando o simulador ns-2, comparando diferentes algoritmos de área de interesse. Os resultados demonstram que a nossa proposta é a que tem a menor utilização de largura de banda, com uma redução em 33,10% do tráfego máximo, e em 33,58% do tráfego médio, quando comparada com outros algoritmos de gerenciamento de interesse. Além disso, em uma arquitetura de servidor distribuído para MMOGs, com recursos heterogêneos, os nodos servidores podem ser facilmente sobrecarregados pela alta demanda dos jogadores por atualizações de estado. Neste trabalho, é proposto também um esquema de balanceamento de carga que utiliza o tráfego de rede como a carga a balancear entre os servidores e tem como objetivos principais: alocar a carga nos servidores proporcionalmente à capacidade de cada um e reduzir tanto quanto possível o overhead introduzido pela própria distribuição. O esquema de balanceamento é dividido em três fases: seleção local de servidores para participarem, o balanceamento em si e o posterior refinamento da divisão de carga. Quatro algoritmos foram propostos: ProGReGA, ProGReGA-KH, ProGReGA-KF e BFBCT. Destes, o ProGReGA foi o que introduziu o menor overhead de todos e o ProGReGA-KF foi o que se mostrou mais eficiente para reduzir o número de migrações de jogadores entre servidores.Traditionally, a central server is used to provide support to MMOGs (massively multiplayer online games), where the number of participants is in the order of tens of thousands. Much work has been done trying to create a fully peer-to-peer model to support this kind of application, in order to minimize the maintenance cost of its infra-structure, but critical questions remain. Examples of the problems relative to peer-to-peer MMOG support systems are: vulnerability to cheating, overload of the upload links of the peers and difficulty to maintain consistency of the simulation among the participants. In this work, it is proposed the utilization of geographically distributed lower-cost nodes, working as a distributed server to the game. The distribution model and some related works are also presented. To address the communication cost imposed to the servers, we specify a novel refinement to the area of interest technique, significantly reducing the necessary bandwidth. Simulations have been made with ns-2, comparing different area of interest algorithms. The results show that our approach achieves the least bandwidth utilization, with a 33.10% maximum traffic reduction and 33.58% average traffic reduction, when compared to other area of interest algorithms. Besides, in a distributed MMOG server architecture, with heterogeneous resources, the server nodes may become easily overloaded by the high demand from the players for state updates. In this work, we also propose a load balancing scheme, which considers the network traffic as the load to balance between the servers, and it has the following main objectives: allocate load on the servers proportionally to the power of each one of them and reduce as much as possible the overhead introduced by the distribution itself. It is is divided in three phases: local selection of servers, balancing and refinement. Four algorithms were proposed: ProGReGA, ProGReGA-KH, ProGReGA-KF and BFBCT. From these, ProGReGA has proved to be the best for overhead reduction and ProGReGA-KF is the most suited for reducing player migrations between servers.

Approved for public release, distribution is unlimitedHuman Systems Integration Report
In the past few years, Massive Multiplayer Online Games (MMOG) have gained in popularity in the gaming industry, the public and the Department of Defense. Improvements to computer technology and the increased data transfer rate over networks have caused the potential applications for networked environments to blossom. MMOGs are a product of these improvements, as technological advancements have made it possible for the masses to gain access to virtual environments and participate. The ability to communicate and interact within the virtual environment has the potential to make MMOG technology an ideal tool for evaluating C4I systems. The design and evaluation of C4I systems with MMOGs has the potential to allow for exploration in the areas of warfighter effectiveness, emergent behavior, collective decision making, human systems integration and effective information flow. This thesis strives to illustrate how a C4I system modeled in an MMOG can aid designers in gathering insights on the effectiveness of the system in various combat situations. The insights will be gathered through the interactions of players with the modeled system in the virtual environment. The human interaction with the modeled C4I system provides the ability to capture the effects of the C4I system on the warfighter. The resultant effects of the C4I system on the warfighter directly contribute to the overall combat effectiveness of the deployed military forces. The background of MMOGs and C4I systems, and attributes of MMOGs that are desirable in evaluating C4I systems are introduced and discussed. FORCEnet, a global C4I architecture still in the conceptual phase is then used as an example to illustrate the potential rewards to using MMOGs to evaluate C4I systems.

Nos últimos anos Jogos Online Massivamente Multijogadores (MMOG) têm se expandido em popularidade e investimento, influenciado, especialmente, pela evolução da conexão residencial (conexões mais rápidas a preços mais baixos). Com o crescimento dessa demanda, surgem problemas na utilização da arquitetura cliente-servidor, normalmente utilizada em jogos comerciais. Entre as arquiteturas alternativas de suporte a MMOGs estão as arquiteturas peer-to-peer. Porém essas arquiteturas apresentam problemas relativos a segurança, problemas esses que possuem, muitas vezes, soluções de baixo desempenho, sendo impraticáveis em jogos reais. Entre os problemas de segurança mais significativos para MMOGs encontra-se o cheating, ou a ação que um ou mais jogador toma para burlar as regras em favor próprio. A preocupação com cheating agravase quando o efeito desse cheating pode causar danos irreversíveis à economia virtual e, potencialmente, afetar todos os jogadores. O presente trabalho faz uso de uma divisão celular do mundo virtual para restringir o impacto de um dado cheating a uma única célula, evitando que este se propague. Para tanto é realizada uma classificação do estado do jogador e utiliza-se uma técnica de detecção de cheating para cada uma das classificações. Foram realizados experimentos através de simulação para testes de aplicabilidade do modelo e análise de desempenho e acuracidade. Os testes indicam que o modelo proposto consegue, de forma eficaz, realizar a proteção da economia virtual, impedindo que a ocorrência de um cheating atinja todos os jogadores.In the past few years, Massively Multiplayer Online Games (MMOG) grew in both popularity and investment. This growth has been influenced by the evolution of residential connection (faster and cheaper connections). With the demand, some limitations imposed by the client-server architecture becomes more significant. Peer-to-peer architectures aim to solve those problems by distributing the game among several computers. However, those solutions usually lack security, or presents low performance. Among the problems, cheating can be considered the most significant to MMOGs. Cheating can be defined as the action taken by a player when this action is against the rules. This may be aggravated when this action can cause irreversible damage to the virtual economy and, potentially, affect all players in the virtual world. This work’s goal is to restrict the cheating impact using a cellular world division. The proposal is to restrict the cheating in a limited virtual space, preventing the propagation. A state classification is presented, and different cheating detection techniques are presented to each element of this classification. Simulation is used to make the experiments aiming to test the performance and accuracy of the proposal. Results indicate that the proposed solution can efficiently protect the virtual economy, restraining the effects of a cheating occurrence to a small portion of the virtual world.

Thesis (PhD)--Stellenbosch University, 2013.ENGLISH ABSTRACT: Recently, there has been significant research focus on Peer-to-Peer (P2P) Massively Multi-user Virtual Environments (MMVEs). A number of architectures have been presented in the literature to implement the P2P approach. One aspect that has not received sufficient attention in these architectures is state management and state persistency in P2P MMVEs. This work presents and simulates a novel state management and persistency architecture, called Pithos. In order to design the architecture, an investigation is performed into state consistency architectures, into which the state management and persistency architecture should fit. A novel generic state consistency model is proposed that encapsulated all state consistency models reviewed. The requirements for state management and persistency architectures, identified during the review of state consistency models, are used to review state management and persistency architectures currently receiving research attention. Identifying some deficiencies present in current designs, such as lack of fairness, responsiveness and scalability, a novel state management and persistency architecture, called Pithos, is designed. Pithos is a reliable, responsive, secure, fair and scalable distributed storage system, ideally suited to P2P MMVEs. Pithos is implemented in Oversim, which runs on the Omnet++ network simulator. An evaluation of Pithos is performed to verify that it satisfies the identified requirements. It is found that the reliability of Pithos depends heavily on object lifetimes. If an object lives longer on average, retrieval requests are more reliable. An investigation is performed into the factors influencing object lifetime. A novel Markov chain model is proposed which allows for the prediction of objects lifetimes in any finite sized network, for a given amount of redundancy, node lifetime characteristics and object repair rate.
AFRIKAANSE OPSOMMING: Onlangs is daar ’n beduidende navorsingsfokus op Eweknie Massiewe Multi-gebruiker Virtuele Omgewings (MMVOs). ’n Aantal argitekture is in die literatuur beskikbaar wat die eweknie benadering voorstel. Een aspek wat nie voldoende aandag ontvang in hierdie argitekture nie is toestandsbestuur en toestandsvolharding in eweknie MMVOs. Hierdie werk ontwerp en simuleer ’n nuwe toestandsbestuur- en toestandsvolhardingargitektuur genaamd Pithos. Ten einde die argitektuur te ontwerp is ’n ondersoek uitgevoer in toestandskonsekwentheidargitekture, waarin die toestandsbestuur- en toestandsvolhardingargitektuur moet pas. ’n Nuwe generiese toestandskonsekwentheidargitektuur word voorgestel wat alle hersiene toestandskonsekwentheid argitekture vervat. Die vereistes vir die toestandsbestuur- en toestandsvolhardingargitekture, geidentifiseer tydens die hersiening van die toestandskonsekwentheidargitekture, word gebruik om toestandsbestuuren toestandsvolhardingargitekture te hersien wat tans navorsingsaandag geniet. Identifisering van sekere leemtes teenwoordig in die huidige ontwerpe, soos ’n gebrek aan regverdigheid, responsiwiteit en skaleerbaarheid, lei tot die ontwerp van ’n nuwe toestandsbestuur- en toestandsvolhardingargitektuur wat Pithos genoem word. Pithos is ’n betroubare, responsiewe, veilige, regverdige en skaleerbare verspreide stoorstelsel, ideaal geskik is vir eweknie MMVOs. Pithos word geïmplementeer in Oversim, wat loop op die Omnet++ netwerk simulator. ’n Evaluering van Pithos word uitgevoer om te verifieer dat dit voldoen aan die geïdentifiseerde behoeftes. Daar is gevind dat die betroubaarheid van Pithos afhang van die objek leeftyd. As ’n objek gemiddeld langer leef, dan is herwinning versoeke meer betroubaar. ’n Ondersoek word uitgevoer na die faktore wat die objek leeftyd beïnvloed. ’n Nuwe Markov ketting model word voorgestel wat voorsiening maak vir die voorspelling van objek leeftye in eindige grootte netwerke, vir gegewe hoeveelhede van oortolligheid, nodus leeftyd eienskappe en objek herstelkoers.

Full textAbstract:
With the launch of World of Warcraft in 2004, Massively Multiplayer Online Games (MMOGs) really came into their own as millions of people started playing worldwide. Providing scalability to such a large audience while maintaining a consistent gameplay experience is a diffcult task which many companies face in an industry where only few succeed. This thesis focuses on the issues of how a MMOG can be scaled to support more concurrent players and how consistency can be maintained in a Distributed Multi-Server Environment (DMSE). As a basis for investigation the notion of "Subgames" (i.e. games within games) was introduced. As smaller, more flexible game units, subgames reduce scalability problems but raise consistency concerns by requiring modular game actions in a distributed environment to function. This is addressed through a new transactional protocol and action framework which abstracts and solves consistency issues while creating an infrastructure which allows for scalability. A complete solution is illustrated using these techniques through the design of general game mechanics and subgames. The approach here further enables scalability of MMOGs in a DMSE and provides a general framework for the further investigation of MMOG consistency and scalability through subgame instances.La popularité des jeux massivement multi-joueurs en ligne ( MMOGs ) a grandement augmenté avec l'arrivée du jeu World of Warcraft, qui est joué par des millions de personnes à travers le monde. Cependant, ce type d'application nécessite des infrastructures extensibles pour accommoder des milliers de joueurs, tout en offrant une expérience de jeu consistante. Ceci représente un grand obstacle que plusieurs compagnies doivent affronter, mais qui est surmonté par peu. Cette thèse aborde les problèmes reliés à la croissance du nombre de joueurs simultanés, tout en discutant comment maintenir un environnement distribué multi- serveurs ( DMSE ) consistant. La notion de sous-jeux ( un jeu qui se déroule l'intérieur d'un autre jeu ) a été utilisée pour mieux étudier le problème. En tant qu'unités de jeu plus petits et flexibles, les sous-jeux facilitent la croissance, mais augmentent les problèmes de concurrence puisque leur bon fonctionnement nécessite des actions modulaires dans un environnement distribué. Ces défis sont adressés par un nouveau protocole transactionnel et un cadre d'applications d'actions qui font abstraction et règlent les problèmes de consistance, tout en offrant une infrastructure qui permet une certaine croissance. Une solution, où les mécanismes de jeux et de sous-jeux sont adaptés en conséquence, illustre les techniques proposées dans cette thèse. Ces techniques permettent une plus grande croissance pour les jeux MMOGs dans un DMSE, tout en fournissant des outils de sous-jeux qui permettent l'étude des défis de consistance et de croissance.

Les jeux massivement multi-joueurs en ligne (jeux MMOGs) visent à rassembler un nombre infini de joueurs dans le même univers virtuel. Pourtant, tous les MMOG existants reposent sur des architectures client / serveur centralisé qui imposent une limite sur le nombre maximum de joueurs (avatars) et sur les ressources qui peuvent coexister dans un univers virtuel donné. Cette thèse vise à proposer des solutions pour améliorer l'évolutivité de MMOG. Cette thèse explore deux services qui sont essentiels à toutes les variantes de MMOG: jumelage et détection de triche. Ces deux services sont les goulots d'étranglement connus, et pourtant les implémentations actuelles restent centralisées. Cette thèse montre également qu'il est possible de concevoir un service d'arbitrage au-dessus d'un système de réputation. Le service résultant reste très efficace sur une grande échelle, à la fois en termes de performance et en termes de prévention de la fraude. Comme l'arbitrage est un problème similaire à la détection de fautes, cette thèse étend l'approche proposée pour surveiller les défaillancesMassively Multi-player Online Games (MMOGs) aim at gathering an infinite number of players within the same virtual universe. Yet all existing MMOGs rely on centralized client/server architectures which impose a limit on the maximum number of players (avatars) and resources that can coexist in any given virtual universe. This thesis aims at proposing solutions to improve the scalability of MMOGs. To address the wide variety of their concerns, MMOGs rely on independent services such as virtual world hosting, avatar storage, matchmaking, cheat detection, and game design. This thesis explores two services that are crucial to all MMOG variants: matchmaking and cheat detection. Both services are known bottlenecks, and yet current implementations remain centralized. This thesis also shows that it is possible to design a peer to peer refereeing service on top of a reputation system. The resulting service remains highly efficient on a large scale, both in terms of performance and in terms of cheat prevention. Since refereeing is somewhat similar to failure detection, this thesis extends the proposed approach to monitor failures. The resulting failure detection service scales with the number of monitored nodes and tolerates jitter

Full textAbstract:
Massively Multiplayer Online Games (MMOGs) can be treated as a database application. Players request actions concurrently to alter the state of objects in the game. Since the world state is the most valuable asset of MMOGs, it is extremely important to ensure its consistency. On the other hand, the defining feature of such games is their capacity to support thousands of clients playing simultaneously, thus requiring scalability. This thesis proposes a solution which leverages typical game semantics and architectures to design scalable transaction models for action handling while maintaining the required levels of consistency. These models vary in their levels of isolation and atomicity and offer different consistency guarantees that are suitable for actions of varying importance and complexity. Action handling protocols are then designed according to those models and optimized for scalability and efficiency. We also present a persistence architecture which is integrated with the transaction models mentioned above. We show how the different consistency guarantees of each transaction model can be maintained by the persistence structure. Concrete actions are then implemented and designed using various transaction models with persistence support. We then evaluate and compare the performance of the various implementations and discuss the trade-off between performance and consistency.Les jeux en ligne massivement multijoueur (MMOGs) peuvent être considérés comme des applications base de données. Les joueurs initient des actions de façon concurrentielle pour modifier l'état du jeu. Puisque l'état du monde est le plus grand atout des MMOGs, il est extrêmement important d'assurer sa consistance. D'un autre côté, la caractéristique essentielle de ces jeux est leur capacité de supporter plusieurs milliers de clients simultanément, et donc l'habileté de gérer une charge grandissante. Cette thèse propose une solution qui est fondée sur des sémantiques et architectures typiques aux jeux pour concevoir des modèles de transaction extensibles à la charge pour la gestion des actions tout en maintenant les niveaux requis de consistance. Ces modèles varient dans leurs niveaux d'isolation et d'atomicité et offrent donc des garanties de consistance variées qui sont adaptées à des actions d'importance et de complexité différente. Des protocoles de gestion des actions optimisés sont alors conçus selon ces modèles. Nous présentons aussi une architecture pour la gestion de persistance des données qui est intégrée aux modèles de transaction mentionnés ci-dessus. Nous montrons comment les garanties de consistance de chaque modèle sont maintenues par la structure persistante. Des actions concrètes sont alors mises en oeuvre et conçues selon les divers modèles de transaction avec persistance. Nous évaluons et comparons la performance de chacune des implémentations et discutons du compromis entre la performance et la consistance.

Full textAbstract:
In recent years, there has been an important growth of online gaming. Today’s Massively Multiplayer Online Games (MMOGs) can contain millions of synchronous players scattered across the world and participating with each other within a single shared game. Traditional Client/Server architectures of MMOGs exhibit different problems in scalability, reliability, and latency, as well as the cost of adding new servers when demand is too high. P2P architecture provides considerable support for scalability of MMOGs. It also achieves good response times by supporting direct connections between players. This thesis proposes a novel hybrid Peer-to-Peer architecture for MMOGs and a new dynamic load balancing for massively multiplayer online games (MMOGs) based this hybrid Peer-to-Peer architecture. We have divided the game world space into several regions. Each region in the game world space is controlled and managed by using both a super-peer and a clone-super-peer. The region's super-peer is responsible for distributing the game update among the players inside the region, as well as managing the game communications between the players. However, the clone-super-peer is responsible for controlling the players' migration from one region to another, in addition to be the super-peer of the region when the super-peer leaves the game. In this thesis, we have designed and simulated a static and dynamic Area of Interest Management (AoIM) for MMOGs based on both architectures hybrid P2P and client-server with the possibility of players to move from one region to another. In this thesis also, we have designed and evaluated the static and dynamic load balancing for MMOGs based on hybrid P2P architecture. We have used OPNET Modeler 18.0 to simulate and evaluate the proposed system, especially standard applications, custom applications, TDMA and RX Group. Our dynamic load balancer is responsible for distributing the load among the regions in the game world space. The position of the load balancer is located between the game server and the regions. The results, following extensive experiments, show that low delay and higher traffic communication can be achieved using both of hybrid P2P architecture, static and dynamic AoIM, dynamic load balancing for MMOGs based on hybrid P2P system.

Massively multiplayer online games (MMOGs) are a popular type of online video game. While these games and their players have been studied previously, there is gap in the literature that examines the relationship between one’s motivation to play MMOGs and loneliness, depression, and problematic use. For this study, 440 players of World of Warcraft (WoW), a popular MMOG, completed a demographics questionnaire and four measures, including Williams, Yee, & Caplan’s (2008) motivation measure, Peter’s & Malesky’s (2008) World of Warcraft-specific Problematic Usage-Engagement Questionnaire, UCLA’s Loneliness scale, and The Depression Anxiety Stress Scales. Results from quantitative analyses suggest that MMO players who are motivated to play for reasons of achievement and immersion are more likely to experience problematic use than those persons who play for social motivations. Loneliness and depression were only positively related with immersion motivated players, and there exists a significant negative relationship between social motivation and depression. These results suggest that gamers who play WoW for immersive reasons are the most at-risk in comparison to their peers. Implications for counseling, limitations, and directions for future research are discussed.

Full textAbstract:
There has been a tremendous growth in the popularity of Massively Multiplayer Online Games (or MMOGs) with millions of players interacting in their virtual game space at the same time. However, the centralized server architecture of most modern day MMOGs is unable to cope with this increase in the number of participating players. Hence, there is a need for a scalable network architecture which can support these large number of players without affecting the overall gaming experience for each player. In this thesis we propose a scalable distributed server architecture which divides the virtual game space in smaller sub spaces and assigns them across a cluster of server nodes thereby reducing the overall load per server. It is based on a distributed publish/subscribe architecture which takes care of client-server as well as server-server communication. We discuss the implementation of this architecture in a real MMOG and experimentally prove that it shows better scalability than the centralized server architecture.

This thesis examined the presentation of self in Massively Multiplayer Online games, to investigate how players create and maintain versions of self in these environments. Key research questions concerned the motivation for engaging in these behaviours, the impact of such activities on their offline lives and for those that did not engage in the active presentation of self, why they did not do this. There were three studies in the thesis, employing a combination of qualitative and quantitative methods. The first study consisted of interviews (n=29), analysed using Grounded theory, and the second an online focus group (n=13 participants) explored using thematic analysis. These results were combined to create a theoretical model for the presentation of self in MMOs. Based on these concept statements a third study (n=408) was created, using an online questionnaire design. Results indicated that a five factor model was the most satisfactory means of explaining the presentation of self in MMOs – with Presentation of the Existing Self, Social Interaction, Gaming Aesthetics, Presenting Different Sides of the Self, and Emotional Impact as the salient factors. Virtual environments are rapidly emerging as a core element of human socialising, as evidenced by the growth of the games industry and the expansion of social networking sites in the last ten years. MMOs represent just one type of virtual environment but also some of the most exciting, since they allow the presentation of multiple versions of self in a fantastical social environment. The thesis adds to the literature through its examination of the presentation of self, in illustrating how and why playe3rs experience and represent their offline self in MMOs. This has not been achieved in any other previously published work and is an original contribution to the literature.

Full textAbstract:
A real-time massively multiplayer online game (MMOG) is a networked computer or video game in which tens of thousands to hundreds of thousands of consumers may interact with one another in real-time in a shared environment, even though these users may be separated by vast geographic distances. Game industry analysis highlights trends indicating that online game usage and market penetration will grow significantly over the next five to ten years. As such, game developers and entertainment companies seek to offer subscription based mass-market online games. However, the risks, costs and complexity involved in the successful development and operation of a scalable online game service are high, in part due to lack of well established and understood models for the network software architecture of such a product. This thesis explores the literature and research regarding distributed military simulation, academic networked virtual environments, and commercial online gaming in search of patterns for network software architectures which are applicable to massively multiplayer online games. It is the hope of the author to contribute to this cross pollination of ideas by providing a thorough review of the techniques and approaches for the design and implementation of large scale distributed systems having properties similar to those found in a massively multiplayer online game system. In this way, perhaps the cost, complexity, and risk involved in building a massively multiplayer online game service can be reduced.Un jeu en ligne massivement multi joueurs en temps réel est un jeu vidéo ou d'ordinateur géré en réseau dans lequel des dizaines à des centaines de milliers de consommateurs peuvent interagir entre eux en temps réel dans un environnement partagé, et ce même s’ils sont répartis dans des régions géographiques très distantes. Les analyses de l’industrie du jeu démontrent que l'utilisation et la pénétration de marché du jeu en ligne se développeront de manière significative au cours des cinq à dix prochaines années. Ceci explique que les développeurs de jeu et les compagnies de divertissement cherchent à offrir à un marché grand public des jeux en ligne basés sur un abonnement. Cependant, les risques, les coûts et la complexité impliqués dans le développement et l'opération d’un service de jeu en ligne sont élevés, dû en partie au manque de modèles bien établis et compris pour l'architecture de logiciels de réseau de tels produits. Cette thèse explore la littérature et la recherche concernant la simulation militaire distribuée, les environnements académiques virtuels gérés en réseau, et le jeu en ligne commercial à la recherche de modèles pour les architectures de logiciels de réseau qui sont applicables aux jeux en ligne massivement multi joueurs. C'est l'espoir de l'auteur de contribuer à cette pollinisation d’idées en fournissant un examen complet des techniques et des approches utilisés dans la conception et l'implémentation de systèmes répartis à grande échelle ayant des propriétés semblables à celles que l’on retrouve dans les systèmes de jeu en ligne massivement multi joueurs. De cette façon, peut-être, le coût, la complexité et le risque impliqués dans la réalisation d’un service de jeu en ligne massivement multi joueur pourront être réduits. fr

Full textAbstract:
This paper reviews the literature on the psychological predictors of the problematic use of Massively Multiplayer Online Role Playing Games (MMORPGs). Nineteen studies were included in the review and results are discussed in terms of seven broad areas; Play time, Demographic differences, Psychological wellbeing and mental health, Personality, Cognitive factors, Physiological factors and Gamer experience and motivations. As a new area of research, the literature at present shows some limitations and inconsistencies across studies. Often factors have been considered in only one published paper, or findings are variable. The most consistent evidence suggests that increased play time is a significant risk factor for problematic use, along with mental health problems and poor psychological wellbeing. The strongest and most consistent predictor of problematic use identified so far appears to be the immersive use of MMORPGs in escaping from real life. Further research should replicate these results and continue to investigate alternative possible risk factors. Longitudinal studies are imperative to differentiate confidently between risk factors and outcomes of problematic gaming, and group comparison studies should include problematic gamers, non-problematic gamers and a non-gaming control group to establish factors associated with problematic gaming specifically as oppose to gaming in general. Studies should consider the impact of age and location of the target population so that results are generalisable to the MMORPG population as a whole. Implication for prevention and intervention of problematic gaming are discussed along with the implications of research in this area on the gaming industry.

Full textAbstract:
Massively Multiplayer Online Roleplaying Games are extremely popular with millions and millions of players spending large portions of their free time in these virtual environments. Still the social value and the meaningfulness of the relationships formed within them are questioned by most non-gamers and even some gamers. In the past even academia was mainly concentrating on the negative aspects of gaming but lately the value and meaningfulness of these relatively new social environments have been getting more and more attention.
This thesis presents a phenomenographic study on how the participants experience meaningful real-life relationships in MMORPGs and how they perceive the effect of the game as the channel for those relationships.
The gathered data revealed four qualitatively distinct ways the participants experienced meaningful real-life relationships in MMORPGs: in-game friendships, beyond the game friendships, comparable to real-life friendships and romantic relationships. These levels have a hierarchical relation in the sense that the previous level has the potential to develop to the next.
Likewise, four distinct ways to perceive the effects of MMORPGs as the channel for relationships were identified in the data. The participants expressed views spanning from one end of the spectrum to the other, ranging from highly positive to potentially negative. MMORPGs could be seen to have a highly positive effect by making different aspects of the relationships easier. In other cases MMORPGs could be seen as just another place to meet people, just a means to an end same as any other medium. MMORPGs could also be considered to be limited when compared to the physical world as a channel and as a result the connections were perceived to be less real in purely online setting. Additionally, MMORPGs were noted to have the potential to become harmful to relationships.
The main contribution of this study are the categories; the levels of relationships and the categories of the effects of MMORPGs as a channel. They can provide a fresh approach into the topic for academia. As for practice, they validate the MMORPG developers’ efforts of encouraging formation of social relationships.

Målgruppen för undersökningen är elever som studerar engelska som andraspråk. Syftet med studien är att undersöka ‘Massive Multiplayer Online’-spels påverkan på elevers språkutveckling i engelska som andraspråk och är en litteraturöversikt på forskning inom området. Materialet består av vetenskapliga artiklar samt en forskningsrapport. Kommunikationsmiljöerna i spelen ses som mer autentiska än de i klassrummet, vilket i sin tur anses leda till ökad språkinlärning och ett stort intresse för att kommunicera hos eleverna. Elever som aktivt spelar ‘Massive Multiplayer Online’-spel på fritiden visar även enligt studierna en högre kommunikativ och vokabulär förmåga inom engelska som andraspråk. Användandet av spelen lämpar sig inte för elever med begränsade engelskkunskaper och används främst av pojkar. Slutsatsen av studien är att MMO-spel i sin nuvarande form inte bör föras in i klassrummet som en allmängiltig undervisningsmetod, utan att spelen ska ses som ett komplement till engelsk språkutveckling.

Full textAbstract:
Massively multiplayer online games (MMOG) have become an extremely popular genre of gaming boasting millions of subscribers. Focusing on cheating, game designers often implement client-server network models which ensure that authority over the gamestate is retained by the game providers. Due to scalability limitations of such architecture the transition to the more scalable, yet less secure, peer to peer (P2P) models has become a more attractive option. Concentrating on cheat detection, the IRS hybrid network model is proposed. It combines positive features from both network designs and represents a reasonable trade-off between security and network efficiency. The IRS model's centralized server acts as the authority over the game-state, managing peer to peer matching and monitoring client behaviour. This allows for a reduced computational load by enabling clients to resolve messages for others. Intermittent peer auditing which compares two client's computation of the same request message also allows for the discovery and elimination of cheating behaviour. By simulating the proposed hybrid model in an abstract game environment designed to incorporate parameters of actual gameplay it is shown that malicious clients are purged extremely quickly and with minimal impact on non-cheating clients, while still ensuring continued benefit and scalability from distributed computation. Since cheating has a very serious impact on gaming it is essential that any study into the improvement of MMOG network models strives to preserve security.Les jeux en ligne massivement multi-joueur (MMOG) sont un genre de jeu devenu extrêmement populaire, avec des millions d'abonnés. Pour éviter les situations de tricherie, les concepteurs de jeux favorisent le modèle réseau client/serveur (C/S) parce qu'il garantie que l'autorité sur l'état du jeu est conservée par le fournisseur du jeu. Cependant, l'évolution de tel modèle est limité. Malgré leur lacune au niveau de la sécurité, les modèles pair-à-pair (P2P) sont une alternative intéressante. Nous proposons un modèle de réseau hybride, l'IRS, qui se spécialise dans la détection des cas de tricherie. Ce modèle exploite les aspects positifs des deux types de modèle réseau (C/S et P2P), tout en proposant un compromis raisonnable entre la sécurité et l'efficacité. Dans le modèle IRS, un serveur centralisé possède l'autorité absolue sur l'état du jeu, tout en assurant la gestion des communications pair-à-pair et la surveillance du comportement des participants. En permettant aux participants d'exécuter des messages pour d'autres participants, la charge d'exécution sur le serveur est réduite. Les cas de tricherie peuvent être découverts et éliminés à l'aide d'audits intermittentes qui comparent les résultats d'exécution d'un même message par deux participants. Des simulations du modèle hybride proposé ont été effectuées dans un environnement jeu visant à reproduire des situations de jeux réelles. Les résultats démontrent le modèle expulse les participants malveillants très rapidement du jeu avec des impacts minimaux aux autres participants, tout en conservant les avantages d'extensibilité des modèles distribués.

This form of online gaming has become a huge phenomenon worldwide both as a popular past time and a business endeavour for many individuals. There are more than 16 million people worldwide who subscribe to fantasy role-playing online games. Although such games can provide entertainment for many people, they can also lead to problematic Internet use (PIU). PIU has also been referred to as Internet addiction, and can cause significant problems in an individual’s functioning. The study aimed to enhance a greater understanding of the phenomenon of male adults’ experiences PIU with MMOG’s. More specifically the study aims to identify if PIU with MMOG’s can be considered a form of Internet addiction within South Africa. Furthermore, assisting in the further development of online addiction diagnosis and treatment strategies. The study utilised an interpretive phenomenological approach (IPA) and participants were purposively sampled. The data was collected using semi-structured individual interviews. Furthermore, Braun and Clarks thematic analysis was used during data analysis while incorporating the four major processes in phenomenological research, namely 1) epoche, 2) phenomenological reduction, 3) imaginative variation and, 4) synthesis. Themes that emerged from the analysis of the participants’ experiences included, initial description of use, motives for continued use of MMOG’s, consequences of PIU with MMOG’s, perceptions of PIU with MMOG’s, and treatment considerations. This study provided a thick description of South African and international literature and combines the literature with the themes that emerged from the participants experiences in order to produce discussions based on the findings of this qualitative study. Conclusions, recommendations, and limitations of this study informed future research on cyber citizenship by providing a detailed understanding of the context of South African male adults’ experiences of PIU with MMOG’s.

Full textAbstract:
Massively multiplayer online games (MMOGs) present fantastic, persistent worlds and narratives for a community of players to experience through pre-defined rules, roles, and environments. To be able to offer the opportunity for every player to try the same experiences, many game developers have opted to create elaborate virtual theme parks: scripted experiences within static worlds that cannot be affected or changed through player actions.
Within these games, some players have turned to role-playing to establish meaningful connections to these worlds by expanding upon and subverting the game's expectations to assume a limited sense of agency within the world. The interaction between role-players and the locations they occupy within these worlds is a notable marker of this narrative layering; specific locations inform social codes of conduct, designed by developers, and then repurposed by players for their characters and stories. Through a qualitative case study in World of Warcraft on public role-playing events, this thesis considers how the design of in-game locations inform their use for role-playing, and how locations are altered through storytelling as a result.

Populations in contemporary Massively Multiplayer Online Games (MMOG) continue to grow, a trend that current client-server architectures are hard pressed to sustain. Application of peer-to-peer concepts and technologies to the domain of MMOG communications can address the issues of scalability and single points of failure associated with the client-server model. A proposed system takes an existing peer-to-peer network overlay as a foundation for peer connection management, and adapts it to have location-awareness by applying the Hilbert Space-Filling Curve. The new routing architecture's location awareness is done with respect to the virtual environment, in order to achieve area-of-interest updates to interested peers with the latency of a single hop. This is done in manner that is fully distributed, thus sharing the work load as evenly as possible across peers without requiring centralized servers. This thesis reviews existing approaches, details the proposed system, and finally presents a proof-of-concept and associated evaluations.

Em geral, jogos classificados como ‘jogos online maciçamente multijogador’, ou massively multiplayer online games (MMOGs) são simulações interativas, competitivas, em tempo real e em larga escala, de mundos virtuais gráficos. Atualmente, a maioria (se não todos) os MMOGs lançados comercialmente são implementados como serviços centralizados, onde centenas ou até milhares de máquinas servidoras, mantidas pelo provedor do serviço do jogo, são responsáveis por executar quase toda a simulação do mundo virtual. Isto implica em gastos significativos em equipamentos e comunicação por parte dos provedores do jogo. Vários trabalhos tentam reduzir o custo de hospedar um MMOG propondo modelos de distribuição da simulação mais descentralizados (peer-to-peer), onde a simulação é movida parcialmente ou totalmente dos servidores (máquinas dos provedores do jogo) para os nós clientes, tipicamente PCs de jogadores conectados por banda larga residencial. Porém, a tentativa de descentralizar um MMOG cria problemas de segurança, na medida em que a simulação passa a ser delegada a nós clientes, que são nós intrinsecamente não-confiáveis que ganham a oportunidade de trapacear no jogo, burlando as regras, visto que as regras da simulação serão executadas por estes. Existem vários tipos de trapaças, mas nós mostramos nesta tese que é possível argumentar que a trapaça de estado (state cheating) e ataques de negação de serviço são as ameaças mais significativas para MMOGs peer-to-peer. Como consequência, nós propomos o FreeMMG 2, um novo modelo de descentralização de MMOGs baseado na divisão do mundo virtual em células que são mantidas individualmente por grupos separados de peers voluntários que executam um processo daemon, não-interativo de simulação. Cada peer de uma célula contém uma réplica completa do estado da célula e se sincroniza de forma tanto conservadora quanto otimista com cada outro peer (réplica) da célula, enquanto ao mesmo tempo recebe comandos de jogo e dissemina atualizações de jogo para as máquinas ‘cliente’ dos jogadores do jogo. Devido à replicação e à seleção aleatória de peers para as células, nós mostramos que o FreeMMG 2 é resistente a trapaça de estado. E, devido ao uso de um peer back-up secreto para cada peer réplica primária da célula, nós mostramos que ataques de negação de serviço contra os peers não irão aumentar de forma significativa a probabilidade de ocorrência de trapaça de estado ou de perda total do estado da célula atacada. Através de simulação de rede, nós mostramos que o FreeMMG 2 é escalável e que utiliza a largura de banda dos clientes de forma eficiente. Assim, mostramos que uma abordagem baseada em replicação de suporte a MMOGs, considerando clientes com conectividade à Internet realística (sem IP multicast e com banda larga doméstica), é viável.Typically, games classified as ‘massively multiplayer online games’ (MMOGs) are competitive, real-time, large-scale interactive simulations of graphical virtual worlds. Currently, most (if not all) commercial MMOGs are implemented as centralized services, where hundreds or even thousands of ‘server’ machines, maintained by the game service provider, are responsible for running almost all of the virtual world simulation. This incurs a significant equipment and communication cost for the game providers. Several works attempt to reduce the cost of hosting a MMOG by proposing more decentralized, peer-to-peer models for distributing the simulation among client (player-owned PCs with consumer-grade broadband) and server (provider-owned) machines, with some going as far as eliminating the need for provider-owned machines altogether. Decentralizing a MMOG, however, creates security issues, as the simulation is now delegated to untrusted client nodes which gain opportunities to cheat the game rules, as the rules are now executed by them. There are several types of cheats, but we show in this thesis that a case can be made for considering state cheating and denial-of-service attacks as the most significant threats for peer-to-peer MMOGs. In light of this, we propose FreeMMG 2, a new MMOG decentralization model based on the division of the virtual world into cells that are maintained individually by separate groups of volunteer peers that are running a non-interactive, daemon simulation process. Each peer of a cell contains a full replica of the cell state and synchronizes both conservatively and optimistically with every other peers (replicas) of the cell, while at the same time receiving game commands and disseminating game updates to actual player machines. Due to its cell replication and random peer selection, we show that FreeMMG 2 is resistant to state cheating. And, due to the use of one secret back-up peer for every primary replica peer of the cell, we show that denial-of-service attacks don’t significantly increase the odds of either state cheating or cell state loss happening. Through network simulation we verify that FreeMMG 2 is scalable and bandwidth-efficient, showing that a replication-based approach to peer-to-peer MMOG support, considering peers with realistic Internet connectivity (no IP multicast and consumer-grade broadband), is a viable one.

Full textAbstract:
Video game localisation has received increased academic attention over the past few years. Despite the call for user-oriented research, few researchers have chosen to focus on issues that are central to end-user experience and its relation to the localised text. With the increased connectivity of gaming in general, and certain game genres in particular, gamers’ language use has become an integral aspect of the game experience. As a result, gamers have become innovative, creating and re-appropriating language, often using non-standard forms to coordinate their gameplay. This innovative and non-standard language, that I call gamer-speak, is the object of my research. In particular, the focus is on the gamer-speak generated by French gamers during group play of two localised Massively Multiplayer Online Role-Playing Games (MMORPGs): World of Warcraft and WildStar. The main aim is to investigate the phenomenon of gamer-speak in MMORPGs and examine its significance for MMORPG localisation. I achieve this through a linguistic analysis and comparison of gamer conversations, analyses of localised texts and its original counterparts, and from survey data collected from active MMORPG gamers regarding their language use. In this thesis I devise an interdisciplinary theoretical and methodological framework for the study of gamer-speak and its influence on MMORPGs which draws principally from Translation Studies and Games Studies. This framework is used to describe the salient features of gamer-speak generated by French gamers when playing the two MMORPGs chosen in the context of Polysystem Theory and Descriptive Translation Studies. The familiarity with and knowledge of French MMORPG players of gamer-speak is determined through surveys. I also examine localised MMORPG text, translated from English into French, paying attention to the role of gamer-speak. Finally, I address the social and cultural implications that gamer-speak has for the target audience of localised MMORPGs. This work adds to our understanding of gamer culture and has implications for game localisation and translation studies.

Thesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management, 2007.This thesis is a part of an exploration of how the relationships between the customers of Massively Multiplayer Online Games (MMOGs) shape customer experience, and can be used to diminish customer churn and improve customer life expectancy, two critical drivers for any subscription-based business model. MMOGs are a very complex product, with a massive level of interaction within the customer base - in fact those interactions constitute a significant part of the appeal. Thus, MMOGs combine aspects of particularly tough online community management, online customer service, and game design/content creation. To be successful, all of those elements need a fine understanding of the customer, their needs and their virtual 'life' and relationships within the game world. This thesis explores the usefulness of detailed, sophisticated interview to gain a fine understanding of customer needs and of the tools necessary to organize communication with, and among, customers. From this knowledge, it projects examples of strategic thrusts necessary to achieve or maintain leadership within this recent, but very powerful and lucrative, business model.

Full textAbstract:
Problematic use of massively multiplayer online games (MMOGs) is an emerging societal challenge worldwide. There are increasing numbers of incident of problematic use of MMOGs and even reported cases of death from playing MMOGs excessively. With its prevalence, problematic use of MMOGs has received increasing awareness from the scientific community, the general public, and the media. Since information systems (IS) research traditionally emphasizes the positive and productive values of system usage, relatively few published studies on problematic use of MMOGs are found in mainstream IS journals. In addition, research on problematic use of MMOGs is hindered by a lack of uniform conceptualizations, valid measurement instruments, and theory-guided study. As a step towards bridging these gaps and fostering the understanding of problematic use of MMOGs, this study aims (1) to conceptualize problematic use of MMOGs and distinguish it from its counterparts, (2) to develop and validate an instrument of it using a rigorous approach (Study 1), and (3) to propose and empirically test a theory-driven model explaining the development of problematic use of MMOGs (Study 2). Study 1 aims to conceptualize problematic use of MMOGs, and develop and validate an instrument of it. First, drawing on the literature of problematic use of MMOGs and behavioral addiction, this study distinguishes among the often interchangeably used terms of “addiction, “problematic use, “excessive use, and “dependence, suggesting that their use requires careful consideration of the research scope and context. Second, following the robust paradigm in the IS literature, the instrument development process is carried out in three stages, including item generation, scale development, and instrument testing. The instrument is empirically validated with 517 active MMOG players. The final instrument, consisting of 37 items, exhibits adequate levels of reliability, convergent validity, discriminant validity, and nomological validity. The validated instrument adds to the repertoire of rigorous research instruments available to future IS researchers, helping to establish a tradition of IS research on problematic use of MMOGs and other hedonic technologies. Study 2 aims to advance theoretical understanding of the development mechanism of problematic use of MMOGs. Drawing on the hedonic management model of addictions, this study proposes a theoretical model explaining how the duality of hedonic experiences, mood enhancement and emotional relief, derived from playing MMOGs lead to problematic use. The research model is empirically tested with 468 active MMOG players with the majority of the hypotheses supported. The findings suggest that both mood enhancement and emotional relief are important mechanisms leading to salience of gameplay, which in turn, explains the development of problematic use of MMOGs. This study adds to the growing body of knowledge on technology usage-related problems and advances theoretical understanding of development mechanism of problematic use of MMOGs. In addition, the findings provide MMOG developers, policymakers, and educators with insights on how to alleviate problematic use of MMOGs

Full textAbstract:
Massively Multiplayer Online Games (MMOGs) are increasing in both popularity and scale on the Internet and are predominantly implemented by Client/Server architectures. While such a classical approach to distributed system design offers many benefits, it suffers from significant technical and commercial drawbacks, primarily reliability and scalability costs. This realisation has sparked recent research interest in adapting MMOGs to Peer-to-Peer (P2P) architectures. This thesis identifies six key design issues to be addressed by P2P MMOGs, namely interest management, event dissemination, task sharing, state persistency, cheating mitigation, and incentive mechanisms. Design alternatives for each issue are systematically compared, and their interrelationships discussed. How well representative P2P MMOG architectures fulfil the design criteria is also evaluated. It is argued that although P2P MMOG architectures are developing rapidly, their support for task sharing and incentive mechanisms still need to be improved. The design of a novel framework for P2P MMOGs, Mediator, is presented. It employs a self-organising super-peer network over a P2P overlay infrastructure, and addresses the six design issues in an integrated system. The Mediator framework is extensible, as it supports flexible policy plug-ins and can accommodate the introduction of new superpeer roles. Key components of this framework have been implemented and evaluated with a simulated P2P MMOG. As the Mediator framework relies on super-peers for computational and administrative tasks, membership management is crucial, e.g. to allow the system to recover from super-peer failures. A new technology for this, namely Membership-Aware Multicast with Bushiness Optimisation (MAMBO), has been designed, implemented and evaluated. It reuses the communication structure of a tree-based application-level multicast to track group membership efficiently. Evaluation of a demonstration application shows i that MAMBO is able to quickly detect and handle peers joining and leaving. Compared to a conventional supervision architecture, MAMBO is more scalable, and yet incurs less communication overheads. Besides MMOGs, MAMBO is suitable for other P2P applications, such as collaborative computing and multimedia streaming. This thesis also presents the design, implementation and evaluation of a novel task mapping infrastructure for heterogeneous P2P environments, Deadline-Driven Auctions (DDA). DDA is primarily designed to support NPC host allocation in P2P MMOGs, and specifically in the Mediator framework. However, it can also support the sharing of computational and interactive tasks with various deadlines in general P2P applications. Experimental and analytical results demonstrate that DDA efficiently allocates computing resources for large numbers of real-time NPC tasks in a simulated P2P MMOG with approximately 1000 players. Furthermore, DDA supports gaming interactivity by keeping the communication latency among NPC hosts and ordinary players low. It also supports flexible matchmaking policies, and can motivate application participants to contribute resources to the system.

Esta pesquisa possui como objetivo geral o estudo do envolvimento e das relações sociais de jovens através dos Massively Multiplayer Online Role-Play Games. Para tanto foram realizados três estudos, um qualitativo e dois quantitativos. O primeiro estudo foi conduzido com 20 estudantes de escolas públicas e particulares da região metropolitana de Porto Alegre e teve como objetivo descrever como ocorre a construção e desenvolvimento de avatares por jovens jogadores para a interação nos MMORPGs. Foram realizadas entrevistas semi-estruturadas e analisadas posteriormente com Análise de Conteúdo. Os resultados deste estudo apontaram 7 sub-categorias relativas à elaboração dos avatares e que foram agrupadas em 3 categorias maiores: Imagem, Função e Motivação. O segundo estudo foi realizado em quatro etapas e teve como objetivo desenvolver instrumentos de mensuração do envolvimento e das relações sociais nos MMORPGs. A primeira etapa foi a construção dos itens baseados na literatura e nos modelos teóricos de Calleja (2007) e de Hinde (1997). A segunda etapa compreendeu o uso de três juízes experts na área. A terceira etapa consistiu em um estudo piloto para a compreensão dos itens com cinco adolescentes jogadores de MMORPG. A quarta etapa compreendeu a análise da consistência interna utilizando-se o alpha de cronbach e das estruturas fatoriais das escalas através de análises de componentes principais e análises fatoriais confirmatórias com uma amostra coletada online de 467 jovens jogadores de MMORPG, com idades entre 12 e 30 anos, de diferentes regiões do país. Os resultados apontaram bons índices de estrutura fatorial e fidedignidade, indicando-se o uso das escalas para pesquisas futuras. O terceiro estudo contou com a mesma amostra do segundo estudo e teve os objetivos de descrever um perfil de usuários de MMORPG; descrever como os jovens usuários vivenciam as relações sociais estabelecidas por eles com outros jovens usuários nos MMORPG; e de averiguar se as características de envolvimento e de relações sociais dos participantes estão relacionadas. Análises estatísticas descritivas e inferenciais foram realizadas, através de correlações de Pearson, e do uso de modelagem de equações estuturais. Os resultados finais da tese indicaram um modelo de relações entre os jovens, seus avatares, o envolvimento no jogo e suas relações sociais no jogo.This research aims study the youth involvement and yours social relationships across the Massively Multiplayer Online Role-Play Games. Therefore, we conducted three studies, one qualitative and two quantitative. The first study was conducted with 20 students from public and private schools in the metropolitan area of Porto Alegre and aimed to describe how is the construction and development of young players avatars for interaction in MMORPGs. Semi-structured interviews were conducted and later analyzed with content analysis. The results of this study reveal 7 subcategories approaching the avatars construction, grouped in 3 major categories: Image, Function and Motivation. The second study was conducted in four stages and aimed to develop scales to measure the involvement and social relations in MMORPGs. The first step was the construction of sentences based on literature and the theoretical models of Calleja (2007) and Hinde (1997). The second stage was the use of three judges, experts in the area. The third step was a pilot study to review the sentences with five teenagers MMORPG players. The fourth step included analysis of internal consistency and factorial structure of the scales with a total sample of 467 young people online MMORPG players, aged between 12 and 30 years, from different regions of the country. The third study involved the same sample of the second study had and the objective of describing a profile of users of MMORPG; describe how young users experience social relationships they established with other youth in the MMORPG users, and to investigate whether the characteristics of involvement and social relations of the participants are related. Descriptive and inferential statistical analyzes were performed. The results indicated a final model of relations between young people, their avatars, the involvement in the game and their social relations in the game.
