"In the end, Sega’s insistence in holding onto these flawed elements transforms what could have been a truly excellent take on the classic Sonic formula, into a messy, ugly beast of a game."—Planet Xbox 360

"Sonic Unleashed takes two steps forward with some of the best speed levels in recent memory, and one step back by tacking on yet another failed experiment with the Werehog."—GameTrailers

"It's like Sega baked a delicious chocolate cake, but mixed a bag of nails into it."—Destructoid.com

"Sonic Unleashed on the Wii is a very different game to its lumpy 360 and PS3 counterparts, and that's a good thing, but it's still not quite a return to form. Stripped of unnecessary narrative nonsense and forced to use new camera views and level designs, it's simply a more satisfying rendition of the same thing, more faithful to the original series and undoubtedly the version that Sonic fans should pick up."—Eurogamer

"They tossed in one of the dumbest "twists" in the history of gaming. A werehog? Really? Stretchy arms? Did anyone actually believe this was going to be fun?"—IGNMetacritic.com: Sonic Unleashed Reviews
