I suspect, nothing less than Nintendo, Sony, or Microsoft going all in on their next generation console would be enough to bring VR mainstream. As in, the VR being the primary way to play.
Of the three, I can’t see Sony or Microsoft doing it.
Maybe Nintendo, as doing weird stuff is kinda their thing, but even that’s doubtful.
Yeah… there were a bunch of issues with the Virtual Boy.
A Sudo 3D experience on hardware that couldn’t handle 3D graphics, needed to be setup on a table, and a color palette that made the GameBoy seem high fidelity, never mind the red was horrid to stare at for too long.
It really was ahead of its time… in all the wrong ways.
