As much as I want VR to be awesome, I've had motion sickness from playing Portal while sitting at a desk. Consequently, I think this is just one of those technologies that I have to be happy for other people to enjoy.
Just FYI, I can't play FPS games without puking, but VR games work for me. The fact that my inner ear matches what I'm seeing in the game makes the difference.
Beatsaber obviously, alyx, in death unchained, superhot. Some of the notable ones I can think of offhand. There's a pretty wide variety of genres though, so depending on if you like action, puzzlers, etc is going to matter a lot. It's also been a year since I've played due to lack of space.
