Operation Flashpoint for xbox hardly ever lagged, the only time it lagged was when me and some friends set like, 400 satchel charges (yes, me and 3 friends spent like an hour and a half just setting satchels) on a runway and detonated them all at once.... hehe, boom.
but im sure the game can hold at least 32 players. it IS a next gen console right? then why arent we playing some real next gen stuff? i dont even want to call it next gen anymore. next gen would be like, arma with 100 vs 100 with no lag and over 1000 bots.... THAT is NEXT GENERATION GAMING. lol. rant over.
