Although Nintendo was the only console manufacturer to market a virtual reality device, SEGA came close to doing so in the 90s, taking advantage of the power of 32X magnification for its Megadrive.

After the success of the Megadrive console, the Japanese company showed a prototype of HMD at the Winter Consumer Electronics Show (Winter CES). According to Electronic Gaming Monthly magazine, such a device would be commercially released in 1993 for about $200 and would come with 4 games, including an adaptation of the success of the Virtua Racing arcade. Graphics were not bad at all for that time, getting to use Gouraud shaders with texture mappings at a time when all the work was done by CPUs and the concept of graphics accelerators was not even in its infancy.
But the device did not pass the prototype phase, being seen for the last time at the Summer CES of 1993, where it was shown by Alan Hunter. The company claimed that the project was canceled because the virtual reality was too realistic and users could injure themselves by moving while using the HMD. Rather, we thought that users would suffer terrible dizziness, given that the headtracking technology of the time left much to be desired and the viewfinders responded quite late to our movements, although we do not doubt the risks that it could involve walking with the viewfinder on, to the point that Oculus continues to clearly indicate that the Rift should be used while sitting.
