And here is a preliminary, not necessarily updated with all the latest things (so, just participate in the thread, duh) list of VR games I can basically recommend, obviously always depending on your preferences (and excluding obvious must have shit like Beat Saber and Half-Life: Alyx):
The Walking Dead: Saints & Sinners has a cool campaign full of great action & some resource scavenging.
Budget Cuts is a stealth puzzle adventure series with nicely integrated teleport mechanics.
Apex Construct is a sci fi immersing adventure game with archery action at its core.
Cubism is a wonderful puzzle game that's sure to entertain your neglected grey matter.
Grapple Tournament is next gen PVP arena FPS with all the classic trappings redefined for VR.
Stormland is an open world shooter, more limited than it seems at first but still fun as hell.
The Room VR is a wonderful continuation of the famous puzzle adventure series, perfectly adapted to VR!
The Thrill of the Fight is a true boxing sim, if less fancy than the gamey Creed and its Rocky license.
Journey of the Gods is a Zelda-lite linear action adventure that's simple but polished and works really well.
Pistol Whip is the new kid on the rhythm game block, I love it like it’s a funky musical Virtua Cop-like.
Drop Dead is a fun riff on The House of the Dead, not nearly as tight but maybe the best of the genre in VR.
In Death is an archery based rogue-lite I spent many hours in early on despite the limited scope.
SUPERHOT VR is a puzzle action shooter with cool slow motion mechanics. Be like Neo!
Eleven: Table Tennis is a table tennis game said to be the most sureally realistic yet with a focus on PVP.
Racket Fury is an alternative table tennis game that is also pretty good with various solo gameplay options.
Catch & Release is a fishing game. Who doesn’t like fishing? I want Twilight Princess fishing in VR now.
Moss is a third person action adventure, you lead a sword wielding mouse as if in a diorama of a fairy tale.
Down the Rabbit Hole is yet another fairy tale adapted to VR, with its own twists, turns and unique style.
Asgard's Wrath is a made-for-VR action RPG with a Viking theme that many gamers enjoyed.
Space Junkies is a PVP zero gravity arena FPS, like Quake in space, great for some instant action.
Ultrawings is a flight game, not quite a sim, maybe a bit like pilot wings, goals and stuff to get through.
Windlands 2 is an action adventure with not-web-swinging and archery, it’s also co-op capable.
Vox Machinae is a PVP focused giant mech combat game with awesome interactive cockpits.
Raw Data is probably the best of the arena/wave shooters with different classes, progression & co-op.
Onward is my favorite “standard” FPS, PVP focused, some co-op & the best feel/controls for weapons/gadgets.
Contractors, Pavlov and other popular VR FPS games put their own twist to the military theme and style of play.
Population: One is atm the most popular VR Battle Royale, it's arcadey with + hair, simplified reloading, etc.
Lone Echo is a must play astronaut adventure, the free PVP Echo VR and its $10 Combat DLC rock too!
Red Matter is another sci fi adventure with a different spin than the above and great interactions.
Dash Dash World is a well made cute kart racing game with solo and multiplayer modes galore.
VTOL VR is a really cool light simulator of combat aircraft with amazing cockpits perfectly suited for VR.
Blade & Sorcery has the best physics based melee combat but doesn’t yet have progression etc.
V-Racer Hoverbike is a cool futuristic racer where you can lean to realistically control your jet moto thing.
Racket: Nx is a unique blend of skill, puzzle and high score fueled shenanigans that's worth checking out.
Pixel Ripped is a duo of games with great nostalgic trips down gaming memory lane in special VR fashion.
There are many more, early access or otherwise. I like where Vengeful Rites is going as a VR RPG with sword wielding, spell casting, the works, Karnage Chronicles is a cool dungeon crawl with co-op and there’s also the free A Township Tale for some online rpging/surviving/crafting, alongside social playgrounds like Rec Room, VRChat, or even Bigscreen. STRIDE is shaping up to be a very compelling Mirror's Edge-like game that takes practice and skill while Crunch Element is a very promising procedurally generated co-op romp through destructible military compounds. VR even has visual novel style games like Altdeus: Beyond Chronos and Spice & Wolf 1 & 2. There are also ports of traditional games, or games that equally support VR and flat gameplay. Titles like Skyrim VR, Phasmophobia, No Man’s Sky, DCS, Elite Dangerous, DiRT Rally 1 & 2, PayDay 2, IL-2 Sturmovik: Great Battles, Star Wars: Squadrons, Project Wingman, Rez Infinite and others are great in VR! Some like Fallout 4 VR weren’t as successful however so some caution is necessary. Others have been converted by fan modifications, MotherVR is a great mod for Alien Isolation, with gamepad/mkb play like PSVR's Resident Evil VII, while the same creator is working on ReclaimerVR, a mod for Halo: The Master Chief Collection that will include hand tracking. Another developer released an Outer Wilds mod that's pretty great and comprehensive. Quake VR is also pretty damn amazing while you can even play the classic Doom engine games and Doom 3 in VR. There's no shortage of great experiences to be had for every gamer.
