Game Engine Black Book: Wolfenstein 3D is one of the better ones I've read this year. It's a fun nostalgia trip, if you played it, and it covers some interesting stuff about historical low-level game programming and quirks of early PC gaming.
I bought that about two weeks ago. It really is a good read. I wasn't around for the game itself, so it's nice that the book introduces the target hardware.
It really was a fun read. Highly recommend to any programmer!
