Footage of canceled 'Sonic Extreme' hoverboarding game

YouTube user ProtonX3 has released a series of videos demonstrating a reportedly canceled Sonic the Hedgehog hoverboarding game for the original Xbox, entitled Sonic Extreme (not to be confused with Sonic X-Treme). Not to cast any aspersions on the potential merits of the game, but the same engine was also used to create a skateboarding game starring anthropomorphic thumbs (also canceled, apparently). But hey, it probably would've been better than Sonic Free Riders, right?

Check out some footage after the break and find a lot more on ProtonX3's YouTube channel.
