A couple months ago I somehow inadvertently got my girlfriend hooked on Modern Warfare 2 and now in gaming in general. We have really enjoyed playing Special Ops together but there's only so many missions on it so it's getting a bit old. I've found most games don't allow split screen multiplayer even if both players have XBL gold accounts so I'm looking for suggestions-- Can anyone recommend some decent games that can be played with 2 people split screen on one Xbox? We've run the whole Rock Band / Guitar Hero thing to death too so at this point we're looking for other games we can play together that won't force me to get a 2nd Xbox and another copy of the game.
