I've played it, the modern stages are a blast, the classic stages are a trip down memory lane, the levels look and feel like they did in their original games. there are two downsides I have: WHERE IS BIG THE CAT, and why did'nt they put Shadow and E-123 Omega in the opening cutscene after the first level with classic Sonic, I mean like after Sonic Adventure 2 Battle and Sonic Heroes, Sonic and Shadow seem to be a little friendly towards each other and on the Sonic Wiki, it says he likes Sonic (to a degree). It's better than Sonic Unleashed, and just might be the best Sonic game on PS3 and Xbox 360.
