Xbox frontman Major Nelson has once again released the latest Xbox LIVE Activity ranking, this time for the week beginning February 7th, and once again Activision and Treyarch’s Call of Duty: Black Ops is king of the chart, remaining the No. 1 most played game on Xbox LIVE.

Call of Duty: Modern Warfare 2 follows in behind, which in turn is followed by Halo: Reach, FIFA 11 and NBA 2K11. Best-selling Xbox LIVE Arcade games for this past week include Serious Sam HD: The Second Encounter, the recently released Stacking (yay!) and Geometry Wars: Retro Evolved 2.

Best-selling Xbox LIVE Indie games (or ‘games’) include Voice Changer 360, Bird Assassin and Toy Stunt Bike.
