My experience with VR so far started with the cheap phone mounts that you put on your face. Wasn't too bad if I'm honest, for watching some videos. I then tried Samsung gear vr. Actually much better with the tracking and UI. But never got much beyond that.
What it would take for me to get into VR is for the price to come down, and that's it. I'm still interested in buying a set, but it would almost primarily be for driving sims, and not much else. I have a pretty elaborate rig and chassis set up, which I think would be great with VR. However, my hang up is the total immersion and cutting yourself from the world for extended periods of time. It would be for short stints only, and that's where the price point comes in.
I would be very keen to try it with games like Subnautica, but only for the exploration part of it. Subnautica can get like Minecraft where you are just grinding like hell for resources for very little progress, and I think wearing the headset for these extremely long periods could have some negative effects on your eyesight and maybe motion sickness.
I'd love to try it for real with Dirt Rally or Assetto Corsa though.
