I don't think it's a gimmick or fad. But PSVR's library still just isn't very good in my opinion. I want to use my headset, but I'm struggling to find content that I enjoy.
So far, Playroom VR has a few fleeting moments of fun. Thumper is a cool, yet limited experience. And REZ is a fun VR experiment that I will not be going back to because I've already been playing REZ for over a decade and the VR controls just make it braindead-easy.
I found RIGS to be very uncomfortable to play as well.
I need a genuine platformer or something I can sink my teeth into that is on par with the level in Playroom VR. Although I don't worry VR as a whole, I do worry that PSVR (specifically) is a fad.
Tonight, I'll try Bound and Tethered in another attempt to get some more time with my headset.
