I surely will. Like i'm playing Halo 2, 3, Wars, ODST, Reach and Anniversary, at least once a week, 'cause i enjoy every Halo game so far, i'm going to play Reach. Campaign, obviously. I don't really care 'bout the multy, not even now.
Like many are still playing CoD 4, Forza Motorsport 3, GoW 2, Mass Effect 2 and many more games. Useless to say.
