For some reason, I'm quite psyched about this game (Borderlands...). Coop first person shooter with random loot almost-RPG-character-skills-developpment-Diablo-esque and gazillions of stuff to pick up and procedurally generated random maps? Well sure, I'm sure the "millions of guns" claim will turn out to be something disappointing, but the replay value in this still seems pretty high. After all, Left 4 Dead only has the co-op part and it was pretty awesome.
