Astrid Ennslin details a discourse analysis/language-based approach to videogame studies, with a focus on how games present information to players, and how players and the public discuss games. Though it takes a long time to get going, once the book really delves into its topic, it gets very interesting, with discussions on how players stake out places in game groups, and how they indicate the nature of play. I imagine a ludology purist wouldn't take very kindly to a text-based linguistic approach to game studies, but I think this approach has something useful to offer.
