Ludologica-critical books on games

An Italian press has published a series of books taking a critical and academic look at video games. The series takes an in-depth look at themes, techniques, context, and other aspect surrounding games. Unlike other books that tries to cover the gaming culture in broad strokes, this series focuses on individual games and dispense with the standards intro to the game which most gamers would already know. These wonderful guides into the study of games should be interesting reads.
