I looked up Sonic Free Riders on YouTube and found out that not only Sonic and Tails have voices, but the main cast does too. Like Knuckles, Rouge, Amy, Shadow, Blaze, Cream, Silver, Jet, Wave...... all those wonderful characters! Wow.. let's just hope Nintendo doesn't change MARIO'S voice. I still want teh game! I have an XBox 360. All I need to do iz buy teh Kinect.. and teh game.
