the best 2palyer RPG co-op game ever.
but you can only pick 3 classes, warrior, hunter and wizard
still, if you have the old ps console(or ps2 or ps3, don't know if they can play this game), try to find this game and sit down with a friend and start playing,
you'll get addicted.
comparing diablo2 and diablo1, like there is much more options in diablo2 and more quests and more weapons, but in diablo1 you don't have the crazy super talents like in diablo2, that's why i like diablo1 so much it's so much fun, a real solid game.
and of course it has 2player co-op.
