The many of us who get motion sickness have simply stopped bothering with VR. Since the market has shrunk anyway after the initial excitement, the few VR games left can afford to be less accessible.

Indeed. I put on any kind of VR helmet for more than 2 minutes and I'll be queasy and/or throw up outright. My level of motion sickness is maybe extreme... but i guess that definitely messes with the total addressable market.

Yeah I appreciate that. There are things like vignetting that can help and newer games do them. But some people will never be able to play them.
