According to data gathered by the NPD for the week ending May 31, Mass Effect had to settle for the second place, still high above the following platoon.

The rest of the top mainly went to either Electronic Arts or Blizzard, with armies of Sims and World of Warcraft dwellers fighting for each step.

Sadly, there were only two exceptions from the Sims/ WoW rule: Call of Duty 4: Modern Warfare and Sins of a Solar Empire, right down in the end of the ladder.

The complete top is down below:
1. Age of Conan: Hyborian Adventures
2. Mass Effect
3. The Sims 2 Double Deluxe
4. World of Warcraft: Battle Chest
5. The Sims 2 Kitchen & Bath Interior Design Stuff Expansion Pack

7. The Sims 2 FreeTime Expansion Pack
8. Call of Duty 4: Modern Warfare
