The Art of Game Design: A Book of Lenses

On one level, this is a textbook about how to design a game. On another level, this is a work of love by someone who clearly understands why games are fun, and how to manage the tricky business of coordinating all the people required to build one. Jesse Schell breaks games down into their individual components, and explains how those can work together to reinforce an experience of fun. The book is full of practical, folksy wisdom on managing artists, programmers, playtesters, and clients. A charming, conversational book full of hard advice and useful ideas. A good read for anybody who loves games, and essential for somebody who plans to design one.
