Cooperation and Disruptive Behaviour – Learning from a Multi-player Internet Gaming Community

In this paper we report possibilities and experiences from employing Counter-Strike, a popular multi-player Internet computer game and its resulting online community in research on cooperative behaviour. Advantages from using this game include easy availability of rich data, the emphasis on team-playing, as well as numerous possibilities to change the experiment settings. We use descriptive game theory and statistical methods to explore cooperation within the game as well as the way the player community deals with disruptive behaviour. After a quick introduction to the basic rules of Counter-Strike, we describe the setup of the Internet game server used. We then present empirical results from the game server logs where cooperation within the game is analyzed from a game theoretic perspective. Finally we discuss the applications of our results to other online communities, including cooperation and self-regulation in open source teams.
