its cuz you are on a ps triple...which is a piece o shit...its just a glorified blu ray player with NO GAMES!
haha you TRULY don't want to get started talking about the shitbox. I owned both, and got rid of the xbox even before my year of XBL was up. First off having to pay extra for EVERYTHING is complete bullshit, no rechargeable controllers? No wifi? No wireless headset capabilities (without spending TONS of money)? I can't trust a company who will knowingly send out products with faults, just to get it out before the competition... and have 75 percent come back to be repaired. The ONLY good thing about xbox is the kinect, in which it doesn't apply to this game at all.
PSN name: irrballsac. add me, mention the forums, I'm usually online nightly. I am at like 4 days in game time, and haven't played single player mode yet... haha, good times though.
I love the game because I can get tons of my friends online to play and talk shit mostly.
