Don't get me wrong you can play games like beat saber ala singstar or rockband taking turns but it's an order of magnitude more if you want the second "controller" and you need much more space. Let alone the equivalent of buying an extra TV for everyone you want to watch a movie with.

When you add on the ergonomics of the device which even with good setups mean you need "heavy" cabling or have limited runtime due to battery it's hard to recommend it to even mates who use their whole weekend on gaming.

That being said I have a Pimax 8k I bought second hand and VR is really an awesome experience when you're in it so it's easy to see why the excitement is still there. I'll also mention some of the extreme sports camera stuff is often 360 if not 3d which benefits from a headset.
