If you want some actual info on Procedural Generation, then watch the talks from Roguelike Celebration. It's a convention focusing on roguelikes, which seem to attract those more interested in the programmatic side of game development. Its got a ton of great technical talks. I haven't watched the remote sessions, but the older in persons are great.
