Other than DCS, Skyrim, and that one Star Wars game at Dave and Buster's where you duel Darth Vader, I don't see a lot that sings to me just yet. Granted, I could easily get 2,000 hours out of DCS over the span of a decade just flying every third and fourth generation fighter jet ever made.
Maybe VR doesn't need that many games because the small handful of good ones have so much depth and replay value. I guess I just talked myself into a $700 VR kit and possibly a $700 GPU upgrade, depending on whether or not my RTX 3060 is up to task.
Not sure what vr kit you're looking at, but if it's a 4k headset to push at 90fps you'll want something more like a 3080 or 4070. But if it's lower resolution it won't need quite so much power.
