Yeah, just tried the demo. It's okay, it controls well and looks pretty nice. But it seems like it's REALLY light on content. Only 3 cars and 4 tracks? And it's only 30 fps? Meh.
I'd buy it if I were swimming in points, but for now I'll wait for a sale. Gotta pick up Clash of Heroes HD, Outland, and Dishwasher 2 first.
