what exactly is a VR headset for?

I’ve never met anyone who speaks well of VR glasses. It also seems that the industry doesn’t innovate much in hardware and software. In my view, there isn’t much to do with them besides playing games, since watching movies seems impossible unless you don’t get very motion-sick. So why buy one? Not all games are compatible with VR.

I think that if someone offered me one for free today, I’d still have to think about whether to accept it or not.
