Call of Duty: WaW has regained the top spot after the release of its Map Pack 1 last week. Gears of War 2 has slipped to the #5 spot, yet with the release of the Title Update 3 patch today and the map pack on the 31st, I’m betting Gears of War 2 will make a run for the #1 spot over the next two weeks. Xbox 360 most played Live titles for the week of March 16th:

• 1. Call of Duty: WaW
• 2. Halo 3
• 3. Call of Duty 4
• 4. RESIDENT EVIL 5

• 6. GTA IV
