I own Oculus Quest 1, I've had it for almost 2 years now, bought soon after 2020 lockdown started, I play singleplayer games.
Standalone, it's okay. Beat Saber and Pistol Whip are good to jump in for a few songs during break when WFH to increase metabolic rate. There are many games on the store and many free games on app lab or sidequest worth trying. As a device, it's a good late-early-adopter device and will be fun for a few months depending on your level of interest in trying innovative but basic games (as opposed to AAA polish and budget).
When connected to PC via wifi, it opens up a whole host of possibilities. PCVR is more mature and with a good PC you can run all the games. I personally find the best ones require the horsepower of a 200+ W graphics card: Half Life Alyx, Lone Echo 1 & 2 (though Echo VR the free multiplayer side is available on Quest), Stormland, Asgard's Wrath, Boneworks, Vertigo.
There are still excellent games on Quest platform: Down the rabbit hole, GORN, blade and sorcery, Moss, Rick and Virtual Virtual reality, A fisherman's tale, Star Wars Vader Immortal. Plus more if you like zombie games (I don't like it in VR). This library is growing as
Facebook Meta is actively investing in this area.
I'd be interested to hear from anybody who has one how much space you need to use one. Do you end up having a dedicated games room?
This is going to sound annoying, but as much space as you have.......
I can play sitting or standing in my study, which is almost 1m across between desks, running danger of hitting the desk, so I usually only play console controller-based game here. I play in the living room on the rug (to avoid tripping on edge of the rug) this is about 2x2m. When not in winter, I play in the conservatory, which is 3x3m. Late evening in summer (no direct sunlight), I can play in the garden over 4x4m.
All spaces work well, the bigger the space, the less often I have to recenter myself when I see the guardian protective lines.
Also, a small number of games can make use of all of the spaces. Tea for God, for example, will generate a place space based on the size of your guardian area, and you physically work about. Its minimum size is 2x2m.
The game did suck, I didn't feel poorly though, I just think there's better ways to "Showcase" VR than some crap "Glowsticks" game.
It becomes a workout when you turn up difficulty to Hard or Expert. It's a good showcase in the 3D-ness of VR experience, also good introduction to motion controls without making gameplay too complicated.
Better showcase for gameplay would be HL ALyx, Boneworks for FPS. GRON, Blade and sorcery for combat, Moss and Down the rabbit hole for third person puzzle.
But TBH, I'm not sure if VR in its current state is for you if you cannot see what Beat Saber is trying to show. Many games are like that: the game evolve around a few basic concept. As I said, it's still an early adopter technology.
