Just ordered a 360 system (yea...i know super late - im normally a pc gamer) & i need a game or two to buy. Only problem is I don't want to buy a game that you beat in a couple weeks and never play again. So with that being said on-line mulitplayer is pretty much a must. I liked what I saw from RAGE but its not on-line MP if I read correctly? Also considering Gears Of War 3 & Mortal Kombat - i know this has been out for a few months now, so are the on-line server/matches for this game still poplulated?
