Ubisoft has revealed some interesting NPD numbers. You know which game sold the most this year in the US, right? Yup, Black Ops. But you know what’s funny? It’s so far ahead of anything else with Just Dance 2 coming second with a measly 5 million sold.

Black Ops did 15 million in the US. That’s right 15 million. Halo Reach sells 4.5 million units, but it has a long way to go to catch Halo 3, which is sitting at 8 million units sold.

You can see all the 10 highest selling games in the chart below. Tell us what you think about these figures.

This was revealed via Nintendo’s NPD statement. Ubisoft must be pleased with this development after third party games used to fare so badly on the Wii. There have been 8 other games that have achieved this feat in the US for Nintendo platforms, according to Nintendo.

They were, Wii Play, Wii Fit, Wii Fit Plus, New Super Mario Bros. Wii, Mario Kart Wii, Super Smash Bros. Brawl and Wii Sports Resort. The game sold 120,000 units in July, which was revealed by NPD.
