a very good example of how frames-per-second stands out is on the DS. I think we can pretty much assume that Mario Kart DS runs at 30fps, give or take, right? then comes the Sonic & Sega All Stars Racing. that game cruises on the DS at a whopping 60fps. it really is that smooth, which is very impressive for a DS title. the sensation of speed is so much better because of the fluid graphics.
anyways, back on topic, this title is starting to really intrigue me. it's like those black & white gravity-based flash games, except you're moving in a 3D sort of open world. i wonder how the gravity works especially on open sky levels, and for how long...
