Sonic Riders: Zero Gravity is a third-person racing game with an anime/manga twist from the masters at Sonic Team. The game is published by SEGA of America, Inc.. Sonic Riders: Shooting Star Story is an alternate title for Sonic Riders: Zero Gravity. Perhaps Sonic Riders: Zero Gravity is being developed for PC, but this version has not yet been announced. Overall, the project turned out to be rather weak. Most reviewers gave the game very low ratings.
