Everything's blurring past and you have no real say in what's going on. In that sense, the game sort of plays itself. There are four-player modes, but that does more to multiply the agony than it does to extract any semblance of fun. Sega could have let EA release the game and call it SSX: Sucky.
First we had Shadow the Hedgehog in his jeep/humvee, and now we've put Sonic on a hover board. Does it strike anyone else as stupid to put characters known for their superior pedestrian speed into vehicles that will only slow them down? Exporting Lara Croft to Crystal Dynamics seems to have done nothing but great things for the Tomb Raider franchise. Maybe Sega should consider doing the same thing with Sonic and Co. They've clearly demonstrated that they either don't know how to make a decent Sonic game anymore, or that they just don't care.
Sonic Riders is rated E (Everyone) by the ESRB for Comic Mischief and Mild Cartoon Violence. This game can be found on: GameCube, PlayStation 2, and Xbox.
