Sonic & Sega All-Stars Racing

Sonic & Sega All-Stars Racing is a kart racing video game, part of the Sega Superstars series, produced for Wii, Xbox 360, PlayStation 3, Nintendo DS (February 23, 2010), and Microsoft Windows (March 3, 2010), featuring characters from Sega franchises. A mobile version has been developed by Gameloft. The game was released for iOS in June 2011, as a paid download. A version for OS X was released by Feral Interactive in April 2013.

The game is also the last in the series to utilize the Sonic's 4Kids Entertainment voice actors (except for Mike Pollock who continues to voice Dr. Eggman). A sequel Sonic & All-Stars Racing Transformed, was released in 2012.

The game is a mascot kart racing game, like other games in its genre like Mario Kart, Konami Krazy Racers and Crash Team Racing. Players can choose to race as one of 20 characters from various Sega franchises such as Sonic the Hedgehog, Crazy Taxi, and Fantasy Zone. Characters race through various race circuits themed on different Sega franchises and collect power-ups to boost their speed or hamper their opponents. The items have a rock-paper-scissors effect, in which certain items can be used to defend against others. Also, on occasions when players get three of one item, they can choose to fire/activate them at the same time. Additional boost can be earned by successfully executing drifts (with longer drifts earning more boost) or performing tricks while in midair. Like Sumo's previous Sega game, Sega Superstars Tennis, each character has a special ability (called an "All-Star Move") unique to them that they may use to their advantage (such as Sonic transforming into Super Sonic and AiAi riding in his monkey ball), which they can obtain if they are running behind in the race. How long each All-Star move lasts depends on the character's current position. Due to network latency issues, All-Star Moves are not featured in online races.
