Juul’s latest, like his Half-Real, offers many insights, particular and general, while being succinct and clear stylistically. The book is not just about matching tile games, although there’s a good chapter on them and their genealogy. It’s about the moment in the history of videogaming where games overflow their “hardcore” niche and begin to appeal to everyone. Juul describes the stereotypes of casual and hardcore games and players; then he demonstrates, using data from many interviews, exactly how they’re wrong. An important, high-level innovation involves figuring out how to study both games and players – in this case, to understand what exactly is meant by “casual games” and how much of what we associate with that has to do with “causal” modes of play. There’s also an excellent analysis of the social space of play in front of the screen, in Guitar Hero and Wii games. A Casual Revolution will be valuable for academics and those in industry, and will help keep the sun shining on games.
