A bit less serious than Jason, but I just finished Derek Yu's "Spelunky":
Spelunky is (IMO) a very unique video game because the mechanics fit together in a way very close to perfection, with nothing superfluous. In this eponymous book, Yu recounts the development process of the game he single handedly designed, and muses on the many creative choices he made, what went well, and what went wrong.
It's a pretty short read, but it has some very good insights regarding game design, and how to design systems intended for players to figure out on their own, rather than hold their hand through tutorials etc. like many games do these days.
