The End of Sonic?
You play as Sonic to start, and eventually you unlock Shadow and Silver, who are basically just a bad attempt at making the game lengthier. There are many glitches during the game, and you'll probably only play one time through. In saying this, the 2-Player co-op mode is alright, if you have a friend who'll actually play with you. Originally, I thought the graphics were nice, until I saw other games on the 360, and was I surprised. Every so often you'll get to play as one of Sonic's many sidekicks, like Knuckles, Tails, Omega, Rouge, Amy, and maybe more, but these characters are just frustrating, and you'll be asking yourself "Didn't I pay for a Sonic game?" The music is awesome, with Zebrahead making the theme "HIs World" It is varied throughout the game, so you may get sick of it by the end of the game.
Basically, Sonic The Hedgehog is a game for ######## fans only, and even then, they will find this annoying. If it weren't for Sonic and the Secret Rings on the Wii, I think this could've been the end of Sonic.
