This game was based on Model 1 hardware and the old Virtuality amiga system and used twin 2' screens on the inside of the headset for a 3D effect. Notes : Jointly developed between Sega and Virtuality. Unfortunately, seeing as it was so expensive to manufacture it was never a stunning financial success for Sega, but it did cement their place in the history books as the world leader in 3D arcade technology, a title which they still hold to this day, and it led to possibly the most popular platform ever, Model 2.Д®mulators : MAME (partial) - Modeler (partial) Virtua racer was the game being written to find out how viable hardware 3D games were, it was never designed to be released, but it was such a success internally they decided to actually release it. Notes : Sega went to General Electric Aerospace (who made the first 3D simulators for NASA in the 1960s) in 1991-92 for assistance to develop a CG platform architecture for their new experimental 3D system, which later became known as Model 1.
