The last game I played that was cel-shaded was Robotech. And though I was a huge fan of the anime, the game wasn't all what I expected it to be. Borderlands is a completely different kind of game, and seems very much what I'm looking for in a shooter these days! Looks like October will see me busy shooting things up both spaceside and planetside!
