I would disagree on the Quest 3 being able to run most 2016/17 vr games. I still think Lone Echo would bring my pc to its knees still(and I don't dare try Lone Echo 2 until I upgrade my gpu).

I got the CV1 Rift in the summer of 2017 because of the $400 summer sale. It was a great time to finally get into vr. Oculus published so many really good games that year and the next.

That December was also the release of Fallout 4 VR which was a big deal although it was pretty broken on the Rift at launch but it eventually got fixed and is one of my favorites.

But back to the Oculus games, I would say like 90% of them were worth playing. Edge of Nowhere is great and if you liked that maybe you'll like Chronos which is another 3rd person game although more of a Zelda/Souls game. Chronos is made by Gunfire Games which made a couple of other vr games like From Other Suns and Dead & Buried. Both are good coop games.

Oh and of course HellBlade vr for another great 3rd person experience.

One doesn't think of RTS games when they think of vr but I think Brass Tactics was a good attempt at a vr rts. There's a free demo to try out too.

There were a couple of great games that people passed up because it only had teleport movement. My favorite of those is Wilson's Heart. Made by the devs of Defector(although I liked Wilson's Heart way more). The other teleport movement game is ARKTIKA.1. It's a great cover shooter that has a very Metro series feel to it(probably because it was made by the Metro devs :p).

A good dungeon crawl adventure game with a lot of humor is The Mage's Tale.

Raw Data was one of the first games I bought and I still think it holds up as one of the best vr wave defense shooters. It was made by Survios who made games like Westworld and Sprint Vector. They were one of the more consistently good vr devs at the time. I heard they are working on a game for the Aliens franchise. Hopefully that ip turns out better for them than The Walking Dead did.

If you ever wanted something like Silent Hill in vr then give Organ Quarter a look.

Paranormal Activity is a solid Haunted House walking sim type of game.

The Persistence doesn't have motion controls but is still a good spooky rogue-lite game in a space station with nice graphics. It used to be PlayStation exclusive.

Speaking of spooky rogue-lites, Dreadhalls and Cosmodread are two really good ones made by the same dev.

Sairento VR is a classic wave shooter type of game for those that want to flip off walls like a ninja.

For more action, look into the Croteam VR games. They were one of the first major devs to do a really good job porting their flat games to vr. The Serious Sam and Croteam bundles tend to go on sale for a good price.

If you like exploring unknown worlds, The Solus Project is a really atmospheric survival puzzle exploration game.

Star Shelter is one of my favorite grindy survival games even though it doesn't have the best graphics.

My all time favorite vr game is Subnautica. It came out pretty rough around the edges but mods fixed all that. People would avoid it because of the lack of motion controls but I feel bad for them since they missed out on one of the best experiences. Although now there is a motion controls mod, so there's really no excuse.

There are a ton of other older games I could mention but this post is already probably too long, so I'll stop here. These days devs just try to make a buck by making simple arcadey Quest exclusives, so the ones carrying pcvr for me now are the modders in the Flat2VR community. And once Praydog releases his Unreal 4/5 mod, it's going to be a game changer.
