Sega went to General Electric Aerospace (who made the first 3-D simulators for NASA in the 1960s) in 1991-92 for assistance to develop a CG platform architecture for their new experimental 3-D system, which later became known as the Sega Model 1 hardware. Virtua Racer was the game being written to find out how viable hardware 3-D games were, it was never designed to be released, but it was such a success internally they decided to actually release it.
