While I play Reach most of all, I play Halo 3 often as well. I tend to play each of the classic games quite often, usually at a random order. I play Reach for matchmaking, Halo 3 for it's campaign and for it's custom games. I would like for more people to play Big Team Battle, my favorite game mode, more often in Halo 3, but I'm not picky. I don't play the MCC at all, I only play the originals.
