Sega Technical Institute once proposed a Sonic the Hedgehog game that adapted the world and characters of the 1993 animated series Sonic the Hedgehog to a new video game. A prototype was developed, but reportedly was rejected by Yuji Naka for its lack of speed, and the game was cancelled. Brief video footage of the prototype has leaked onto the internet.[255][256]
