I bought it a while back, and I'd be willing to play with you (though at the moment my PC is undergoing maintenance, so I won't be able to play it for a week or two, due to the fact that I'm stuck on my Mac). It is a fun game, just make sure to play with a group of 4 or you will get bored real fast. Imho, none of the DLC is worth it in this game, though I do own all of them but the newest one (but if they come in the pack on sale, then by all means, go for it).
The game doesn't have a difficulty level, which kinda turned me off the game at first, due to the fact that it does tend to be hard at certain points in the game.
