Unfortunately, the Xbox 360 version of Supreme Commander has just been delayed. The game, which hoped to introduce 360 gamers to the RTS game was looking good and seemed to work nicely with the controller.
Here's the official word:
"Aspyr has been working feverishly with partners Gas Powered Games and Hellbent Games to put the finishing touches on the Xbox 360 version of Supreme Commander. Recently, after a thorough assessment, we decided that it would be in the best interest of the product to delay the launch. This small delay will put the game on store shelves later this spring or early summer."
