Twesterm, it's a multiplayer game, but the big selling point of L4D is the AI Director...it controls when and where zombies spawn. If the gamers are wiped out after a huge fight, the Director will slow things down for tension...then release another wave at the right time.
It checks for your mood and stress based on what's going on to play procedural scary music...and this AI Director, by its nature, will work on any custom map you give it...which is really awesome, no more drawing bot paths for the AI to walk around on.
I'd definitely give L4D the AI award hehe.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
