A 16-bit platform game icon reinvented in a multi-gravitational 3D world. Spherical stage effects with an vast sense of scale and gallons of design innovation. A game which simultaneously pushed the series into the future and distilled everything that was great about its history. Super Mario Galaxy? No, Sonic did all that stuff first. Ten years before the Wii was even launched in fact. So why did the plumber get all the glory? Simple. Sonic's game was never released.
