I think your benchmark is wrong. I spend ~15 hours a week gaming, and maybe 1 hour a week on VR (averaged). That feels like a fair amount of use in VR, but it's nowhere near 7-8 hours/week. I'm not sure I'd want to spend 8 hours a week in VR.

But the experiences I've messed with are amazing when they land. Elite Dangerous, Beat Saber, Moss, even Google Earth. It's pretty rare for a game to make me stop and literally exclaim, "Holy shit!", but it happens pretty regularly in VR.
