Awesome game but...
Why put this under role-playing? By no stretch of the imagination is this a role-playing game. No stats, basic item drops, and that's about it. Items aren't persistent like in a regular RPG. Don't classify a game as an RPG when it really isn't one.
Really love the game however. Much better with 2+ people playing. Half the fun is killing your friends!
This game is amazing, simply put. I'm not usually a third person gamer, but this game made me change my mind. It has awesome gameplay, humorous characters, and clever references and achievements. And it has co-op too! I'm suprised that it doesn't cost more! At this price, it's a steal! Only con I hacve to give it is that the graphic are really high end, so unless you have a good graphics card, then your are going to have a bit of trouble.
