I already have it for the 360 but I may end up getting the PS3 version as well. Play on whatever system has a good group of OS guys assembled at the given moment
I was finally able to get in some matches today. Played a few rounds with Phobia from OS.
As far as the PS3 version goes, how is the lag?? For me, the lag has not been much of a problem thus far on the 360 side. If the PS3 has any kind of crippling lag issues, I'll save my money.
