Hey everyone. I'm looking for a really demanding game for the iPhone. Something that slows down, freezes, crashes or otherwise looks good but is often difficult to work with. Nothing poorly made, but something where I can show the power of the PowerVR SGX in the iPhone 3G S compared to the PowerVR MBX-Lite in the 2g and 3g. Doesn't have to be free, and credit will be given. I don't mind if its your's or not just as long as it meets the criteria. Thanks!
