Book excerpt: How the tools and concepts for making games are connected to what games can and do mean; with examples ranging from Papers, Please to Dys4ia. In How Pac-Man Eats, Noah Wardrip-Fruin considers two questions: What are the fundamental ways that games work? And how can games be about something? Wardrip-Fruin argues that the two issues are related. Bridging formalist and culturally engaged approaches, he shows how the tools and concepts for making games are connected to what games can and do mean.
