The other day I had another go on a PSVR headset, just to see some more trailers and play another part of a game. See this communication about why I had to sell my PSVR. One of the trailers I watched was me strapped in a chair being attacked by what looked like a zombie. This was mostly fine.
Then I played a Call Of Duty demo where I was flying a space ship. I probably managed about thirty seconds before I had to stop as the feelings of sickness were rising.
It was a good thing that I sold the PSVR (which saddens me).
