The only Sonic game to not feature Dr. Ivo "Eggman" Robotnik.
Only available for the Nintendo Wii.
First sonic game to feature British voice actors.
Sonic and the Black Knight alongside Sonic and the Secret Rings were originally meant to be part of a Wii exclusive spinoff series known as the "Storybook Series", placing Sonic and co. in ancient fairy tales such as the knights of the round table. The series was abandoned due to both games poor reception.
The music that plays during the fan art gallery is a Violin Remix of the song "It Doesn't Matter", Sonic's theme (Sonic Adventure 2 version).
