I was thinking about getting VORPX, I had a few questions for people who have it before I get it:

1) What's the % of games are to get running? There's a lot of late 90s/early 00s games I want to play in VR, would most them even be playable with vorpx or is it certain engines or modified games that make it easier?

2) How difficult is it to setup? There are guides for certain games, but if I played an experience with no guide would I be able to figure out how to make it work?

3) Generally, is is worth it overall? I just want some more VR ports, and this is the best I can hope for
