OH MY GOD SC3 IS FUGGIN SA-WEEEEET!!! That coop stuff is THE next best thing in gaming I believe right now. Online gaming was close to Coop, but NOTHING as of right now makes me think otherwise. What's better than calling your friend to help you out in a game where u are stuck!? Plus all of the FUN that is to be had in coop/online play.
GAHH SC3....HL2.....D3 coop.....GAHHH!!! *brain blows up*
