Sonic R is a racing video game developed by Traveller's Tales and Sonic Team and published by Sega for the Sega Saturn and Microsoft Windows as part of the Sonic the Hedgehog series. The game was released in North America on October 31, 1997, and in Europe, Australia and Japan later the same year. It was re-released for the PlayStation 2 and Nintendo GameCube as part of the Sonic Gems Collection.
Sonic R is the third Sonic racing game and the last of two Sonic games to be co-developed by Traveller's Tales and Sonic Team. In the game, players can take control of one of ten Sonic series characters and participate in races on various Sonic-themed race tracks. The game's story focuses the characters' efforts to win a series of races and prevent Doctor Robotnik from stealing the Chaos Emeralds and enslaving the world.
Sonic R was praised by critics for being one of the few Sonic games featuring 3D computer graphics on the Sega Saturn but was also criticized for its poor game controls and short length.
