Alright, i'm going off the 360 version here, but there's not much difference aside from graphical quality.

Sonic Generations is probably the second best 3D Sonic game, after Sonic Colors. The game is not perfect, but it is a blast to play through. You will come for Classic Sonic and stay for Modern Sonic. The side-missions while hit or miss, will keep you playing for a nice while, as is collecting the red rings. The final boss is a pretty big pain, but otherwise a small mark on an otherwise great game.

Sonic the Hedgehog is back!

I just dropped a helicopter into a big hole and the whole base blew up and thisg ame was totally worth the money
