We have one, my husband wanted it. It is fun. Was great to fly an X wing on battlefront. And the Spiderman homecoming trailer is awesome.
Only problem is I am not good at flying games and got really bad motion sickness. You really do have to take lots of breaks from it.
I don't like the price... (Seems a lot and I'm worried that it will get broken. Although we have had it for 6 months ish now and it is fine.)
£350 for just the headset. Although cheaper than other headsets. The camera which is needed for it to work is not included, so closer to 400, it comes with a couple of demo games. Husband now has Farpoint, which came with a gun, and the move controllers which are really good for Star Trek bridge crew. It is good for parties etc. Games in the playroom ( giant sea monster on headset chasing little robots on the controllers. Cat chasing mice. Ghost hunting.
Deep sea diving on the VR worlds game is really good too. So as for is it worth it? My husband would say yes.
