An experimental study of communication and coordination in noncooperative games
No full textThis paper reports the results of an experiment designed to test the usefulness of alternative solution concepts to explain players' behavior in noncooperative games with preplay communication. In the experiment subjects communicate byplain conversationprior to playing a simple game. In this setting, we find that the presumption ofindividualisticandindependentbehavior underlying the concept of Nash equilibrium is inappropriate. Instead, we observe behavior to becoordinatedandcorrelated. Statistical tests reject Nash equilibrium as an explanation of observed play. The coalition proof correlated equilibrium of the game, however, explains the data when the possibility of errors by players is introducedPublicad

Coalition-proof equilibrium
No full textWe characterize the agreements that the players of a noncooperative game may
reach when they can communicate prior to play, but they cannot reach binding
agreements: A coalition-proo[ equilibrium is a correlated strategy from which no
coalition has an improving and self-enforcing deviation. We show that any correlated strategy whose support is contained in the set of actions that survive the iterated elimination of strictly dominated strategies and weakly Pareto dominates every other correlated strategy whose support is contained in that set, is a
coalition-proof equilibrium. Consequently, the unique equilibrium of a dominance
solvable game is coalition-proof.Publicad
Video game addiction: past, present and future
No full textGaming addiction has become a topic of increasing research interest. The last decade has witnessed a significant increase in the number of empirical studies examining various aspects of problematic video game play and video game addiction. This paper begins with a brief past history of how research into video game addiction has changed over the last three decades (i.e., the 1980s, 1990s and 2000s). It then examines more thoroughly the contemporary research literature by analyzing the (i) prevalence of problematic video game use and video game addiction, (ii) negative consequences of excessive video game use, (iii) factors associated with problematic video game use and video game addiction, and (iv) the treatment of problematic video game use and video game addiction. The paper concludes by looking at the trends in the field and a somewhat theoretical examination of what the future of video game addiction might be.Mark D. Griffiths, Daria J. Kuss and Daniel L. Kin
Understanding Computer Role-Playing Games: A Genre Analysis Based on Gameplay Features in Combat Systems
No full textA game genre as diverse as that of computer role-playing games is difficult to overview. This poses challenges or both developers and researchers to position their work clearly within the genre. We present an overview of the genre based on clustering games with similar gameplay features. This allows a tracing of relations between subgenres through their gameplay, and connecting this to concrete game examples. The analysis was done through using gameplay design patterns to identify gameplay features and focused upon the combat systems in the games. The resulting cluster structure makes use of 321 patterns to create 37 different subgenre classifications based solely on gameplay features. In addition to the clusters, we identify four categories of patterns that help designers and researchers understand the combat systems in computer role-playing games
On Some Myths about Sequenced Common-valued Auctions
No full textEquilibria are constructed for classes of game models of sequenced second-price auctions having identical common-valued objects. In some of these the equilibrium price falls on average, and in others the seller loses on average by committing to announce publicly something that he knows. Both of these possibilities are surprisesPublicad
Dark Patterns in the Design of Games
No full textGame designers are typically regarded as advocates for players. However, a game creator’s interests may not align with the players’. We examine some of the ways in which those opposed interests can manifest in a game’s design. In particular, we examine those elements of a game’s design whose purpose can be argued as questionable and perhaps even unethical. Building upon earlier work in design patterns, we call these abstracted elements Dark Game Design Patterns. In this paper, we develop the concept of dark design patterns in games, present examples of such patterns, explore some of the subtleties involved in identifying them, and provide questions that can be asked to help guide in the specification and identification of future Dark Patterns. Our goal is not to criticize creators but rather to contribute to an ongoing discussion regarding the values in games and the role that designers and creators have in this process
Undercurrents – A Computer-Based Gameplay Tool to Support Tabletop Roleplaying
No full textThis paper introduces Undercurrents, a computer-based gameplay tool for providing additional communication and media streams during tabletop roleplaying sessions. Based upon a client-server architecture, the system is intended to unobtrusively support secret communication, timing of audio and visual presentations to game events, and real-time documentation of the game session. Potential end users have been involved in the development and the paper provides details on the full design process
Teaching-learning concepts to develop game-based and fun European handball classes
No full textEuropean Handball is one of the most popular invasion games in Brazilian schools. As the game is played on a futsal court, using similar demarcations and goalposts - and as nearly every Brazilian school has a futsal court - the adjustment to European handball is easily made, enabling the involvement of thousands of school-aged children in the game. The aim of this work is to present and discuss three teaching-learning concepts which have been used over 15 years in Brazil to develop game-based strategies that engage children in Handball practices
On The Foundations of Digital Games
No full textComputers have lead to a revolution in the games we play, and, following this, an interest for computer-based games has been sparked in research communities. However, this easily leads to the perception of a one-way direction of influence between that the field of game research and computer science. This historical investigation points towards a deep and intertwined relationship between research on games and the development of computers, giving a richer picture of both fields. While doing so, an overview of early game research is presented and an argument made that the
distinction between digital games and non-digital games may be counter-productive to game research as a whole
