VR Systems? And Games?

1

About two months ago, I built myself a new PC. I’ve been doing so for years, and have found reselling the old parts really cuts into the overall expense of the thing, plus I get it to look just how I want. Anyway, now that I have, it turns out I have pretty capable VR-ready machine. If you’re into nerdy computer parts, this is what I have going on: https://pcpartpicker.com/list/ZtxT9W

VR systems seem pretty expensive, but I’ve come this far. Is this worth diving into? If so, which systems are getting the most looks and what games really make it worthwhile? VR is 100% new to me, so any/all suggestions welcomed.
