Many real-world applications require artificial agents to compete and coordinate with other agents in complex environments. As a stepping stone to this goal, the domain of StarCraft has emerged as an important challenge for artificial intelligence research, owing to its iconic and enduring status among the most difficult professional esports and its relevance to the real world in terms of its raw complexity and multi-agent challenges. Over the course of a decade and numerous competitions 1 – 3 , the strongest agents have simplified important aspects of the game, utilized superhuman capabilities, or employed hand-crafted sub-systems 4 . Despite these advantages, no previous agent has come close to matching the overall skill of top StarCraft players. We chose to address the challenge of StarCraft using general-purpose learning methods that are in principle applicable to other complex domains: a multi-agent reinforcement learning algorithm that uses data from both human and agent games within a diverse league of continually adapting strategies and counter-strategies, each represented by deep neural networks 5 , 6 . We evaluated our agent, AlphaStar, in the full game of StarCraft II, through a series of online games against human players. AlphaStar was rated at Grandmaster level for all three StarCraft races and above 99.8% of officially ranked human players. AlphaStar uses a multi-agent reinforcement learning algorithm and has reached Grandmaster level, ranking among the top 0.2% of human players for the real-time strategy game StarCraft II.

PurposeAs business is becoming more global, virtual teams are getting increasingly prevalent. The purpose of this paper is to examine virtual team effectiveness by taking a deeper look at the Virtual World Teams (VWTs) of Massively Multiplayer Online Games (MMOGs).Design/methodology/approachThe paper investigates the effects of leaders’ emotional intelligence and transformational leadership on virtual team effectiveness, including three sub-factors of team effectiveness: team performance, viability and team member satisfaction. In addition, the indirect effect of emotional intelligence on team effectiveness via transformational leadership was examined. In total, 500 MMOG players that belonged in virtual world teams participated in the study. Hypotheses were tested through a series of multiple linear regression analyses, and one-way ANOVA tests were used to explore the impact of gender on the key factors of team effectiveness.FindingsThe analysis revealed a significant predictive relationship between perceived leader emotional intelligence and virtual team effectiveness sub-factors, mediated by transformational leadership behavior. Further analysis revealed gender differences in players’ perceptions of their leader emotional intelligence, transformational leadership and virtual team effectiveness.Practical implicationsThis paper adds to the literature by revealing important predictors of virtual team effectiveness. These findings suggest implications for research and practice in the fields of Human Resources (HR), Human Resource Development (HRD) and training programs for e-leaders. The results of the analysis based on gender differences also have theoretical and managerial implications.Originality/valueThe study provides evidence that transformational leadership mediates the relationship between leaders’ emotional intelligence and team effectiveness in a virtual team.

This study investigates user behaviour in massively multiplayer online games from the perspective of their intentions to engage in real money trading. Players who engage in real money trading purchase resources instead of spending time to acquire them in the game. This behaviour influences not just their own gaming experience, but those of other players as well as the operator’s revenues. We present an online survey which targets the players of World of Warcraft. Players’ relationships with real money trading are investigated using insights from behavioural economics. We propose a model which includes a set of behavioural determinants grounded in empirical research on online games. The study’s findings indicate that a player’s social status and the disinhibiting effects of online play are positive influences on players’ intentions to engage in real money trading, while perceived fairness, anticipated regret and uncertainty about the seller’s behaviour are negative influences. Interestingly, neither the perceived enjoyment nor the potential punishments influence intentions.

Many hands make light work A natural polypeptide chain can fold into a native protein in microseconds, but predicting such stable three-dimensional structure from any given amino-acid sequence and first physical principles remains a formidable computational challenge. Aiming to recruit human visual and strategic powers to the task, Seth Cooper, David Baker and colleagues turned their 'Rosetta' structure-prediction algorithm into an online multiplayer game called Foldit, in which thousands of non-scientists competed and collaborated to produce a rich set of new algorithms and search strategies for protein structure refinement. The work shows that even computationally complex scientific problems can be effectively crowd-sourced using interactive multiplayer games. Predicting the structure of a folded protein from first principles for any given amino-acid sequence remains a formidable computational challenge. To recruit human abilities to the task, these authors turned their Rosetta structure prediction algorithm into an online multiplayer game in which thousands of non-scientists competed and collaborated to produce new algorithms and search strategies for protein structure refinement. This shows that computationally complex problems can be effectively 'crowd-sourced' through interactive multiplayer games. People exert large amounts of problem-solving effort playing computer games. Simple image- and text-recognition tasks have been successfully ‘crowd-sourced’ through games 1 , 2 , 3 , but it is not clear if more complex scientific problems can be solved with human-directed computing. Protein structure prediction is one such problem: locating the biologically relevant native conformation of a protein is a formidable computational challenge given the very large size of the search space. Here we describe Foldit, a multiplayer online game that engages non-scientists in solving hard prediction problems. Foldit players interact with protein structures using direct manipulation tools and user-friendly versions of algorithms from the Rosetta structure prediction methodology 4 , while they compete and collaborate to optimize the computed energy. We show that top-ranked Foldit players excel at solving challenging structure refinement problems in which substantial backbone rearrangements are necessary to achieve the burial of hydrophobic residues. Players working collaboratively develop a rich assortment of new strategies and algorithms; unlike computational approaches, they explore not only the conformational space but also the space of possible search strategies. The integration of human visual problem-solving and strategy development capabilities with traditional computational algorithms through interactive multiplayer games is a powerful new approach to solving computationally-limited scientific problems.

Massively Multiplayer Online Game (MMOG) dependency has been widely studied but research results suggest inconclusive antecedent causes. This study proposes and empirically tests three predictive models of MMOG dependency using a survey of online gaming participants. It finds multimedia realism for social interaction serves as an original antecedent factor affecting other mediating factors to cause MMOG dependency. These mediating factors derive from Uses and Gratifications theory and include: (1) participation in a virtual community, (2) diversion from everyday life, and (3) a pleasant aesthetic experience. Of these, participation in a virtual community has a strong positive relationship with MMOG dependency, and aesthetics has a modest negative relationship. Moderator analyses suggest neither gender nor “frequency of game playing” are significant but experience playing online games is a significant moderating factor of MMOG dependency.

The popularity of massively multiplayer online role-playing games (MMORPGs) has grown enormously, with communities of players reaching into the millions. Their fantasy narratives present multiple challenges created by the virtual environment and/or other players. The games' potential for education stems from the fact that players are immersed in a virtual world where they have the opportunity to manipulate and explore, thus motivating the construction of knowledge. The interaction and collaboration between participants allows students to exchange information, test their understanding and reflect on what they have learned. Given the promising results of using MMORPG technologies for educational purposes, this paper translates the multiplayer role playing game (MRPG) aspect, the essential concept behind MMORPGs, into the classroom context. We present the abstraction behind a Classroom Multiplayer Presential Role Playing Game (CMPRPG) and the development of a CMPRPG for teaching ecology. The game has a quest structure in which each result highlights a key teaching objective. It is implemented at a high level, with interaction between reusable game elements defined using triggers. It is observed that the implemented CMPRPG has appropriate usability levels, benefits the learning and application of the concepts of ecology and, in the interactive dimensions, it encourages participation and collaborative narrative structures among participants.

A variety of online support groups exist for \"gaming widows\" who feel their spousal relationship has been displaced by time spent playing Massively Multiplayer Online Role-Playing Game(s) (MMORPGs). MMORPG research has been presented on youth and adults, however to date, there is no research on married gamers to support or refute the claims of discontented spouses. The purpose of this study was to gain a better understanding of the gaming behaviors of couples who play MMORPGs. The sample included 349 couples. Results indicated lower marital satisfaction related to couples' MMORPG gaming interactions such as quarrelling about gaming, not retiring to bed at the same time, and addictive gaming behavior. Positive effects of gaming together were also identified.
