One of the best Nintendo Wii games I have ever played
24 May 2010 | by (Fairfax, Virginia, USA) – See all my reviews

SONIC UNLEASHED, in my opinion, is one of the best Nintendo Wii games I have ever played. Even though addition, even though I've never made it to the last level, I still enjoy the game. When I first started playing this game, I didn't even know how to pass the first level. Also, I must say that the graphics on this game are absolutely outstanding. Everything that happens when the moon rises in the beginning will surely make your eyes widen. Before I wrap this up, I'd like to say that the people at Nintendo know how to keep video game fanatics entertained. Now, in conclusion, if you're a video game fanatic, this is definitely one you'll want to play and own. If you're a Sonic fanatic, this one comes highly recommended from me.
