I dont know what the big deal is with halo... the multiplayer is definately fun, and the single player is for a little while, but the level design is SOOOO freakin' uninspired. Once you get 4 levels deep, I think they just said 'the hell with this' and made every room in the level look the same... My roomate and I are trying to get through it in co-op mode, but we can only finish one level at a time without basically putting a gun to our respective heads and pulling the trigger.
anyways, my pic right now for best xbox game? Jet Set Radio Future.
