Living City, A Collaborative Browser-Based Massively Multiplayer Online Game

This work presents the design and implementation of our Browser-based Massively Multiplayer Online Game, Living City, a simulation game fully developed at the University of Messina. Living City is a persistent and real-time digital world, running in the Web browser environment and accessible from users without any client-side installation. Today Massively Multiplayer Online Games attract the attention of Computer Scientists both for their architectural peculiarity and the close interconnection with the social network phenomenon. We will cover these two aspects paying particular attention to some aspects of the project: game balancing (e.g. algorithms behind time and money balancing); business logic (e.g., handling concurrency, cheating avoidance and availability) and, finally, social and psychological aspects involved in the collaboration of players, analyzing their activities and interconnections

Paving the way to e-services: Innovation through online games

The transformative power of organizational and service innovations on value or supply chains has been the object of several studies. The question identified in this paper is how disruptive trends in the videogames world can have spill-over effects in the broader realm of e-services. Section 1 opens with a brief review of literature. Section 2 proposes a description of the on-line games industrial ecosystem, the characteristics of the production process and the value chain in the online video games industry. The main techno-economic models for the production and distribution of online games are described in a third section with an emphasis on service creation, and illustrated by some case studies. The last part highlights the trend of innovative paths towards an economy of e-Services which are driven by the evolution of online games in a converged environment. --Online value creation,virtual world,virtual good,value chain,digital content convergence,new business models,services

Analyzing the effect of tcp and server population on massively multiplayer games

Many Massively Multiplayer Online Role-Playing Games (MMORPGs) use TCP flows for communication between the server and the game clients. The utilization of TCP, which was not initially designed for (soft) real-time services, has many implications for the competing traffic flows. In this paper we present a series of studies which explore the competition between MMORPG and other traffic flows. For that aim, we first extend a source-based traffic model, based on player’s activities during the day, to also incorporate the impact of the number of players sharing a server (server population) on network traffic. Based on real traffic traces, we statistically model the influence of the variation of the server’s player population on the network traffic, depending on the action categories (i.e., types of in-game player behaviour). Using the developed traffic model we prove that while server population only modifies specific action categories, this effect is significant enough to be observed on the overall traffic. We find that TCP Vegas is a good option for competing flows in order not to throttle the MMORPG flows and that TCP SACK is more respectful with game flows than other TCP variants, namely, Tahoe, Reno, and New Reno. Other tests show that MMORPG flows do not significantly reduce their sending window size when competing against UDP flows. Additionally, we study the effect of RTT unfairness between MMORPG flows, showing that it is less important than in the case of network-limited TCP flows

Social gaming: A systematic review

Digital games often constitute a shared activity where people can spend time together, communicate and socialize. Several commercial titles place social interaction at the center of their design. Prior works have investigated the social outcomes of gaming, and factors that impact the experience. Yet, we lack a comprehensive understanding of how social gaming has been approached and explored before. In this work, we present a systematic review covering 263 publications, gathered in February 2021, that study gaming experiences involving more than one person, with a focus on the social element that emerges among partakers (players and/or spectators). We contribute with a systematized understanding of (1) how the topic is being defined and approached, (2) what facets (mainly in terms of outcomes and determinants of the experience) are being acknowledged and (3) the methodologies leveraged to examine these. Our analysis, based on mixed deductive and inductive coding, reveals relevant gaps and tendencies, including (1) the emphasis in novel technologies and unconventional games, (2) the apparent negligence of player diversity, and (3) lower ecological validity associated with totally mediated evaluations and a lack of established constructs to assess social outcomes

Born Digital / Grown Digital: Assessing the Future Competitiveness of the EU Video Games Software Industry

This report reflects the findings of the JRC-IPTS study on the Video games Industry, with a focus on two specific activities: online and mobile video games. The report starts by introducing the technologies, their characteristics, market diffusion and barriers to take up, and their potential economic impact, before moving to an analysis of their contribution to the competitiveness of the European ICT industry. The research is based on internal and external expertise, literature reviews and desk research, several workshops and syntheses of the current state of the knowledge. The results were reviewed by experts and in dedicated workshops. The report concludes that the general expectations for the next years foresee a speeded up migration of contents and services to digital, in a scenario of rapidly increasing convergence of digital technologies and integration of media services taking advantage of improved and permanent network connections. The role of the so-called creative content industry is expected to increase accordingly. Communication services and media industry will co-evolve on the playground of the Internet of services, along with a product to service transformation of the software market in general. In this general context the Video games Software industry plays and is expected to play a major role. The games industry may become a major driver of the development of networks as it has been in the past for the development of computer hardware.JRC.DDG.J.4-Information Societ

The Industry and Policy Context for Digital Games for Empowerment and Inclusion:Market Analysis, Future Prospects and Key Challenges in Videogames, Serious Games and Gamification

The effective use of digital games for empowerment and social inclusion (DGEI) of people and communities at risk of exclusion will be shaped by, and may influence the development of a range of sectors that supply products, services, technology and research. The principal industries that would appear to be implicated are the 'videogames' industry, and an emerging 'serious games' industry. The videogames industry is an ecosystem of developers, publishers and other service providers drawn from the interactive media, software and broader ICT industry that services the mainstream leisure market in games, The 'serious games' industry is a rather fragmented and growing network of firms, users, research and policy makers from a variety of sectors. This emerging industry is are trying to develop knowledge, products, services and a market for the use of digital games, and products inspired by digital games, for a range of non-leisure applications. This report provides a summary of the state of play of these industries, their trajectories and the challenges they face. It also analyses the contribution they could make to exploiting digital games for empowerment and social inclusion. Finally, it explores existing policy towards activities in these industries and markets, and draws conclusions as to the future policy relevance of engaging with them to support innovation and uptake of effective digital game-based approaches to empowerment and social inclusion.JRC.J.3-Information Societ

A Survey of the Ability of the Linux Operating System to Support Online Game Execution

Linux has suffered sluggish home user uptake due mainly to the dominance of rivals, and has seen numerous incarnations as a gaming platform fall flat. Gaming is a particularly sensitive application given its intensive bandwidth and system response requirements; these applications therefore place specific demands on the Operating System platform on which game play is supported. In this work, the ability of the Linux operating system to support execution of online games is explored through a survey of the state-of-the-art in this area. Given the recent increase in cloud-based online gaming, it can be concluded that the time is ripe for more widespread Linux uptake, especially in the gaming domain. This is particularly true today given the amount of exposure to Information Technology across society in general, and ongoing deployment of Internet of Things environments: Linux's open source, modular and freely customisable design may therefore not be as daunting as before, and the unique benefits of this platform may be exploited for the experiences it can bring to applications in general and, specific to the context of this work, players in their game play. This paper makes a unique contribution to the field: Although a number of articles are available within the general area of Linux and gameplay, a thorough survey on this issue has not been seen so far. This is therefore the gap to which this paper contributes

Perfil de la investigación académica sobre Juegos Masivos en Línea para Múltiples Jugadores (JMLMJ) 2000-2009: Horizontes para la investigación educativa

DOI: http://dx.doi.org/10.17227/01234870.38folios75.94Whilst there exists a large body of publications around Massively Multiplayer On-line Role-Play Gaming (MMORPG), there is little profiling academic research on this type of game. This study aims at unveiling what, when, where and who constitute scholarly work in research about MMORPG. A 777-register dataset was configured with primary documents taken from 16 databases and two web-portals. The dataset was drilled down using specialized text-mining software. Findings revealed four main research interests that comprise the games themselves, gaming experiences, systems architecture and educational MMORPG. It was also found that research on this topic started out in 2002 and some milestones of emerging research were charted out. The most prolific organizations and authors were also identified in which the USA, Canada and Italy occupy outstanding places. It is recommended that research profiling studies be carried out to extendmore informed literature reviews and support further research questions.La investigación sobre Juegos Masivos en Línea para Múltiples Jugadores (JMLMJ) es amplia; sin embargo, no hay mucha literatura especializada que perfile la investigación sobre este tipo específico de juegos.
