Nintendo can be happy, as its titles took the first, second and third prize and added up to nearly 15 million units: Wii Play, followed by Mario Kart Wii and Wii Fit.

In fact, the top trio sold almost as much as all the other titles in the top. And speaking about the others, don’t be amazed when seeing Grand Theft Auto IV, Gears of War 2 and Call of Duty: World at War in the middle of the top. We weren’t amazed either:

1. Wii Play – 5.28 million units
2. Mario Kart Wii – 5 million units
3. Wii Fit – 4.53 million units
4. Super Smash Bros. Brawl – 4.17 million units
5. Grand Theft Auto IV – 3.29 million units
6. Call of Duty: World at War – 2.75 million units
7. Gears of War 2 – 2.31 million units
8. Grand Theft Auto IV – 1.89 million units
9. Madden NFL 09 – 1.87 million units
10. Mario Kart DS – 1.65 million units
