Game books

I was reading a book on game programming at a friend's the other day but I don't remember the name.  I'm not really interested in playing or programming games, but I am interested in real-time systems.  Are there any decent game programming books that focus more on algorithms/theory/design/etc than on graphics?

/prog/ is a secret community of anus haxists, metatrolls, Sussmen, and Satori Programmers who revel in the joy of abstract bullshite.

Don't expect them to do ``game programming'' or any such lowly activity.
