I believe you are right about Chen adding “more evidence to one side of an established debate”, but I guess we perceive the value of this slightly different. If anything I think his rich empirical backing of his claims are sorely needed in the field of Games and Learning – a field that sometimes appear to be so busy convincing everyeone that “games are good for you” that they dont have to time to delve into the ‘failures’.

Chen aptly demonstrates how his guild was a vibrant and functioning community of practice, and how it still wasnt robust enough to deal with the emergent playstyles that developed during their time together.
