Yea, from pure end consumer standpoint I guess I wouldn't buy it either.

PlayCanvas is pretty dope, e.g. http://seemore.playcanvas.com this runs at ~20-30fps and that's on a shitty builtin Oculus Go Snapdragon SoC... so for somewhat small but nice scenes, the hardware is enough (it actually can't use your Desktop hardware at all, besides hacking it the shit up I guess, like streaming PC games as video or something).

My brother bought PS-VR with Resident Evil, but he only played a few times, he hates to setup all the cables
