Sonic 3D: Flickies' Island, known as "Sonic 3D Blast" in the US, was released on the Sega Genesis and Saturn in 1996, and also released later on the PC.
The music in the Genesis version, however, is widely considered to be some of the greatest in the series, and has spawned numerous remixes across the web.
Note: The game was perfectly planned, we could not find glitchs to gain advantages.
