Sonic Extreme probably wouldn’t have set the world on fire – the poor old blue blur’s had a patchy few years, bless him – but a new video offers an insight into yet another game that withered on the vine. A racing game involving Back To The Future 2-style hoverboards, Sonic Extreme would have been a riff on the old Mario Kart (or Sonic Drift) template. Taking in familiar locations from the main videogame series – most strikingly Green Hill Zone – Sonic Extreme would have seen the famous hedgehog and his friends compete in a series of downhill races. There were coins to collect, power-ups, ramps and other boosts you’d expect from an arcade racer. Sonic Extreme was dreamed up by a developer called Vision Scape, who effectively made the game on spec; they put together a concept and pitched it to Sega, who were initially receptive to the idea – until, eventually, the project collapsed.
