I'm buying a Xbox One the day the MCC comes out. Mostly to play Halo: CE. Halo 2 was EASILY the most disappointing Halo game to come out. It was by far the biggest step back in terms of gameplay and skill when compared from the gaps from H2 to H3 and to H4.
I still played Halo 2 for countless hours and got 4 or 5 playlists in the 40s however.
