Mystic Monkey wrote: Yeah, gameplay be similar to Sonic Generations, especially stage layouts for Classic and Modern. Except Classic is set in the past and Modern set in the future... and you can switch from classic/past to modern/future at times, similar to Sonic Unleash where you cat switch to Werehog and Hedgehog. So like Sonic Generations, you could have Classic in the Modern World, & Modern in the Classic World.

It might work the same for Project Sonic 2017 too?
