In the right hands, the iDevices are incredibly potent gaming rigs. 2XL Supercross, named after thestudio that developed it, has the kind of pedigree that explains its spectacular first impression. After all, 2XL is quite familiar the racing genre, having developed BAJA for the Xbox 360 and PlayStation 3 in addition to several Xbox driving games. Apparently, they were able to scale that technology to this new screen to create a gorgeous supercross game that just dropped into the App Store. But gameplay is king and that's how some of the air comes out of 2XL Supercross' tires.
