I'm going to try to come up with an original concept for this. Maybe it's not actually Sonic you're playing as? Maybe it's a simulation that Tails made and you're helping him test it out? Then you could have a cyber highway kinda' deal.

Sonic GT is already doing that. I'd rather not steal their level design concept. Nah, maybe something like a utopian city in the tropics?
