After messing up the numbers last week, Xbox Live’s Major Nelson has reported the numbers for this week. Bungie’s Halo: Reach takes down Infinity Ward’s Call of Duty: Modern Warfare 2. No miscalculations, no crying foul. Reach is at the top of the list, with the most unique users playing the game this past week. Now, just how long can it hold onto number one? My guess is until November 9th.
