This year's September software sales hasn't quite reached the levels of last year's Halo 3-driven numbers, going down 6% for overall sales of US$ 616 million. Nevertheless, some multiplatform and first-party titles have managed to post impressive figures.

Despite some backlash from critics, LucasArts' multiplatform release, Star Wars: The Force Unleashed (Xbox 360, PlayStation 3, Wii, PSP, DS) still sold over a million copies, half of which was for the game's Xbox 360 version.

Nintendo's Wii Fit also continued to put up some big numbers along with EA's Rock Band 2 (PlayStation 3, Xbox 360, Wii).

Here are the top ten games in terms of units sold for September:

1. Star Wars: The Force Unleashed (Xbox 360) - 610,000
2. Wii Fit (Wii) - 518,000
3. Rock Band 2 (Xbox 360) - 363,000
