After an incredibly successfuly holiday period for Call of Duty: World at War, it’s no surprise that the game has come out on top on the list of most played Xbox LIVE title.

The familiar old face of Halo 3 is still there at No. 2, while Gears of War 2, at No. 3, manages to trump yet another older yet enormously popular game, Call of Duty 4, which sits at No. 4. Left 4 Dead, another popular title on LIVE, is at No. 5.
