Sonic the Hedgehog and his friends, among them Tails, Knuckles, and Doctor Eggman, meet characters out of SEGA's other best-selling cames, such as B.D. Joe from Crazy Taxi, Ryo Hazuki from Shenmue, Ulala from Space Channel 5, and Billy Hatcher from Billy Hatcher and the Great Egg for a kart racing challenge in the best-selling Sonic & SEGA All-Stars Racing for the PlayStation 3, Xbox 360, and Nintendo Wii. Now you can race your SEGA favorites outside the game with these R/C vehicles of Sonic and Knuckles. Pick up your controller and send your vehicle tearing off down the sidewalk!
