One of my friends also has a KAT Walk C2 and I've played Skyrim VR on that. It takes a bit to get used to but it's a lot of fun.
I bought a Bigscreen Beyond 2 + 5090 gpu basically just to play DCS (Digital Combat Simulator, a flight sim with full fidelity figher jets that you can even fly in PvP multiplayer) and it's the coolest thing VR has to offer for me. All my relatives and friends who tried it were stunned too.

This guy on X gave me some suggestions of top tier VR games:
Hubris, Into The Radius, Wanderer, Blade & Sorcery, RE4 Remake, Modded Skyrim VR, Modded Minecraft, Vertigo 2, Arken Age, Half Life 1 & 2 VR, UNDERDOGS, Hitman VR, Pixel Ripped Series, Walking Dead, Propagation Paradise Hotel
You play James Bond, except that for various silly reasons you find yourself stationary, and you have psychic powers to reach far away stuff because, again, stationary. "They've trapped Bond in a bathysphere!" "You're in a car in a jet ful of poisonous gas that's going to explode!" Each level will kill you quickly and hilariously over and over until you figure out a sequence of steps to survive.
And then there are the racing sims. I find these are such an immersive experience it reaches an uncanny-valley type feeling for me, where my body is expecting G-forces that never come, or gets confused with the steering wheel not being the exact same size as my eyes are seeing. It's great though, and definitely recommended if you enjoy cars at all.
