Shadow the Hedgehog

[GameMaster]

Any true Sonic fan will boycott this game. I refuse to play any Sonic game that doesn't star Sonic. And I don't want some lame storyline about Sonic and Shadow being the same person or Shadow being a variation of Sonic in another dimension or Sonic being infected by an evil slime and turning into a evil Shadow form of himself.
