Once again, Call of Duty: World at War takes the No. 1 spot in the Xbox LIVE Activity stakes, while Halo 3 is still managing to stay up there at No. 2.

In fact, the top five games on LIVE are unchanged from last time, with Gears of War 2 at No. 3, Call of Duty 4 at No. 4 and Left 4 Dead at No. 5. The second half of the activity chart is nicely mixed up this week, though, with new contender, the multiplayer demo of Lord of the Rings: Conquest hitting the No. 9 spot.
