Sonic Extreme (Cancelled 2003-2006 Xbox Game)

Not to be confused with Sonic X-Treme.Sonic Extreme is a cancelled skateboarding video game in the Sonic the Hedgehog series for the Xbox. While the game was never officially released, footage of the game was received very poorly by the video game press.

Many critics supported Sega's decision to cancel the game. Game Informer commented that it looked "terrible" and "predictably awful". Computer and Video Games described it as "basically another utterly rubbish skateboarding spin-off". Similarly, VG247 called it "compellingly awful". TeamXbox, while less negative, still noted that the gameplay and level design is still pretty basic. For unknown reasons the spin-off never appeared on the internet until May 1, 2011, footage of the game was uploaded up to YouTube, which was labeled by Game Informer as a "skateboarding spinoff' video game.
