A very small VR setup, with a multi-directional treadmill, which can easily fold in under the sofa. Drop anything but first person gaming, just make that work.

A very small VR setup, with a multi-directional treadmill, which can easily fold in under the sofa. Drop anything but first person gaming, just make that work. Oh and make it PS5 and Xbox compatible. Gamers want to walk Skyrim, or the Fallout wasteland, but if it's just a set of goggles on your face then what's the point? You could just get a bigger TV. I doubt that you can actually do it, with current tech, but $60B and we're no closer? It's still just a set of goggles.
