Don’t know if it was ever announced to be in development and existed in any form outside of being told there was going be 3 games, but would absolutely love to have seen what the 3rd Sonic book game would have been like. I still need to play the Black Knight game, but would absolutely hop on board the 3rd if it existed.

That, and would absolutely LOVE if Sega uncanceled the Riders series. Best racing game series to ever exists in my opinion. Too bad the 3rd game sucked so hard it caused the beautiful rose that is the Riders series to wither away.
