Let me get the factors out of the way. We will do this like the PROS!!!

Concept: Take all of the good, and bad, out of past sonic games, and put it in a 2D perspective for one half, and a 3D perspective for the other half of the game.

Graphics: Bright colors make this the best looking sonic game ever, although the graphics are kind of pixel-y on the 360 version.

Sound: Mix your favorite sonic tunes (once you unlock them) into classic and modern sonic levels.

Playability: Classic sonic controls like he did in the retro games, but modern sonic is still kind of slippery.

Entertainment: You will be remembering your childhood with this genesis throwback.

Replay Value: High

Final Verdict 9.25/10
