Only two Wii titles feature in the top ten, with the high-profile Legend of Zelda: Twilight Princess dropping out of the top twenty all together.
Two Pokemon titles sit at the top of the charts, with Pokemon Diamond selling over 123,000 units and Pokemon Pearl another 97,000 copies, according to Media Create.
The top seven titles in the charts are all DS games, including Kirby Squeak Squad at number three and New Super Mario Bros. at number five.
At number eight is Wild Arms 4 for the PlayStation 2, while Wii Sports and Pokemon Battle Revolution are the only two games for Nintendo's new home console, at nine and ten, respectively.
