As a metal music listener with fond memories of Guitar Hero, I’ve enjoyed Ragnarock a ton.
You play as the drummer on a viking boat, hitting the notes (similar to GH) to the tune of power metal. Nice workout, especially if you really get into it and start exaggerating your movements.
I have no killer game, but I enjoyed many games. The most notables for me were I expected you to die series, A Fisherman's tale series, the last clockwinder, Synth Riders, Superhot
Personal favorite: Cosmodread. It’s a procedurally generated spaceship horror game where you must gather resources and not get killed by monsters to escape.
- Walkabout mini golf (20h). Great for unwinding and the ball physics are nearly perfect.
- I Expect You To Die, 1 & 2 (15h). If you like puzzle games, these are fantastic. Super addicting the first time you play, but little replay value.
- Demeo. Like D&D-lite (10h). Can play co-op with other Quest users or with Steam on PC.
- Half Life 2 VR mod and Half-Life: Alyx (10h). I loved HL2 when it first came out so there's a massive nostalgia bonus, but Alyx is widely acclaimed.
- Pistol Whip (2h, but getting into it). This is a spiritual successor to beat saber.
