I think it would still work. A lot of people claim VR is about immersion, but I disagree. There is nothing less immersive than having a giant headset strapped to your face. To me VR is about the control scheme. Playing games with your hands with full freedom is very different to playing with a standard controller. That wouldn't be affected by a lack of 3D vision.

Some VR games assume you have depth perception and so you may have trouble with them, such as Beat Saber, but I honestly think most VR games would be perfectly playable without 3D vision. You may not be as good at the games as someone with 3D vision, but you'd probably still enjoy it.

My second favourite VR game is Gorilla Tag. I think that would play fine without 3D vision... as long as you don't get motion sickness - that game can be a lot.

You mean people blind in one eye? I think it still works, but obviously depth perception will not be there
