New equipment may be too expensive and novel for home purchases, but an arcade could invest in those fancy omnidirectional treadmill and VR gloves.
The demand is there. People pay $30+ for a spin class, why not VR lightsaber zumba?
Video games in the 80s and movies started off in commercial locations before becoming cheap enough for home use. I'm not sure why VR hasn't followed their model. I've assumed it was because the tech isn't there yet.
