It is quite a good game, but does make a little rip-off.
The Bad: Darn SEGA, they turned Sonic into a stupid werehog!
I do like this game, but the werehog part makes me sometimes hate the game. The PS2 version is different to x360 and PS3, but everyone says this one is better. Sonic goes slower in this and has less things to jump on, while on x360 and PS3, you can boost for like ages and you have basically everything to jump on.
Moving on the werehog, the attacks are quite boring, but some of the adventures are pretty cool, but usually, I think it's a little boring.
I would say that, Sonic Unleashed is worth playing. I will tell the hedgehog controls here.
