Depends on the game. Most games allow you to be seated. Sim games (why I bought VR) require you to be stationary. A top seller like Beat Saber has you standing but you don't walk around you stand still except for some minor stepping to the side.I see the need for larger open space is also a major issue, I certainly haven't got a good spot in my house without destroying my place in the process too xD
You haven't played VR have you?
