facts are halo is just very dull and boring for the all the hype and 2 year wait. this was projested to be the big team game of the year (cpl and shit) but CS, DoD, Bf1942, Ut2k3 all blow it away for multi play.
ps if you haven't tried the multi play don't worry about it, its just as dull and boring as the rest of the game (the jeeps with 3 people in them provide the only entertainment, but it gets old fast.
