I have to think it’ll stay an arcade and power user thing indefinitely. The full experience needs large, clear section of your house, and housing is getting more expensive. Break down your costs per sq ft and see that you’re paying an awful lot for it.

Games like Beat Saber don’t have to move around too much, but the experience will always be limited if games have to keep the player in one spot and can’t use room scale. That said, Beat Saber can be pretty decent cardio workout if you put effort into swinging your arms (as opposed to lazily flicking your wrists around). Sweat buildup on the headset can be an issue, though. Keep some alcohol wipes around.

Racing/airplane sim stuff is one of the best uses. People who are into that are willing to drop a lot of money.
