Got an og Vive (699.99 cdn at the time came with headset, controllers, and base stations), playing the hell out of that headset just over a year in steam VR playtime at 2 - 4 hrs a day. I have played Half-Life:VR mod (due to the age of the actual game it is my worst port experience) Half-Life 2: VR mod, Half-Life 2 ep 1 and 2 in VR (absolutely amazing) Raft:VR mod (a few bugs and a few abilities missing from flat, but overall flawless) The Forest:VR mod(excellent), and let’s not forget Valheim:VR mod.
Quest garden can be limiting but you can plug your quest (air link, ?whatever? desktop, link cable) and pretty much play anything on steam, personally have 90+ titles under my VR library (no beat saber). You can check yt for people playing these flat2vr games
There is a game called cyubeVR on steam and PS2VR, built from the ground up for vr. It is a great fun game with a solo dev. Highly suggest checking it out, there are quite a few videos on it and it is highly modable. It is sad that the big cos are dropping support
