Following the completion of Sonic 3 and Knuckles, Yuji Naka was offered the role of producer at Sega of Japan.

Sonic Team USA was the United States division of Sonic Team located in San Francisco, California.

The newly established Sonic Team USA was so influenced by their new San Francisco location, that the level designers of the game, Takashi Iizuka and Eitaro Toyoda, designed some of the levels, such as the City Escape, Mission Street, Radical Highway, Route 101, and Route 280 levels as references to major San Francisco locations.

The album was at best hoped to be a minor success on par with Sonic Youth's Goo, which Geffen had released a year earlier.

The following year, BioWare released Sonic Chronicles: The Dark Brotherhood on the Nintendo DS, its first title for a handheld game console.
