Yeah, I had the chance to try VR for once. Honestly I did not enjoy it much.
I went to a theater which have the facilities, where you have to ware VR and see the 'Galaxy' on the screen they are playing. I am not sure why I got headache and saw blurry for some moments.
But my partner enjoyed it a lot. May be I use -2.25 powered glass that's why. I don't know.
Try it yourself. You will get a new experience for sure.
No, I have not tried out any virtual reality technology. But I could have. And I probably still could. My brother's friend (or the common-law husband of his mother) have some kind of virtual reality stuff for his smartphone. They live together. My brother tried it out last year, and maybe earlier. I don't know. But they probably still have the device (I assume they didn't sold it, and both the phone and the device are still working), so I could probably try it out, if I would visit them. They live approximately 27-30 km away from me.
I knew someone with an Oculus Rift dev kit, and I've tried a few of the mobile VR headsets. The high quality development games are great. I really enjoyed it. Some of the low end mobile devices or low quality (or low frame rate) visuals can cause an awful headache and nausea for me.
