I totally agree about "room scale games". Has add-on benefits of getting out of the house and getting some exercise. Here's my idea (shh - don't tell anyone). Buy an abandoned roller skating rink and transform it into a VR game space. Of course this assume that some other entity will create one or more compelling games to be played in your space.

I also love this idea, but it still has many barriers. Principal technical issue is that these headsets are not wireless, which means you would need anot overhead motor system to follow you around as you walked.
