Hey! I just got a 360 a few weeks ago and have been loving it, loving Gears of War, and plan on getting Halo 3 tonight at midnight. Having never played a Halo before do I need to play the first two games to fully enjoy this game? Or is it something I can just hop right in? I'm getting it really for the mulitplayer which I hear is phenomenal, but I do intend on playing through campaign mode too.
