The 1990s was an incredible period of transition in the video game world. For the early part of the decade, Nintendo had been working on its ‘Project Reality’ with SGI, in its attempt to bring “photorealistic” 3D graphics to consoles. Sony became a newcomer to the console market, with similar ambitions. Nintendo’s efforts later became the legendary and history-making Super Mario 64 on the Nintendo 64 and Sony’s the cult-classic Crash Bandicoot on the original PlayStation.
Meanwhile, struggling Sega was wondering how to fight back. The company was developing a game called Sonic X-treme that was to be Sega’s first fully 3D Sonic game. However, it was not to be. It’s development was not at all free from trouble, with the title eventually being cancelled.
Fortunately, a copy of the unfinished game was discovered in 2006, and now, fans have joined together to release a version that can run on Windows. Be warned though, it really is nowhere near finished. The ‘game’ is essentially a playable demo, one not free from bugs. The video below however, helps us to get an idea of what Sonic-equivalant of Super Mario 64 may have looked like.
