I've been playing the crysis beta. It's not even that good. The graphics are great but team fortress 2 is a way better (multiplayer) shooter. I'm hoping (and willing to bet) that Crysis's single player will be pretty good, but the multiplayer has been pretty generic thus far.

 i don't wanna play it for the multiplayer either, just for the best graphics ever shown to mankind
