Personally, I find Elite: Dangerous to be the best, most immersive VR game I've played. It's a 6DOF space sim set in a 1:1 scale version of the Milky Way that puts you in the pilot's seat, with a few dozen ships to choose from. The insides of the cockpit (or bridge on the larger ships) are fully modeled. Paired with a decent HOTAS or dual-stick setup, it's about as close as you're going to get to flying a futuristic…
I have to admit, a vr space sim could be pretty awesome. I've played a lot of oolite and I used to play another space Sim pretty heavily the name which escapes me right now. >surface exploration and you can have friends join you on your ship as either a gunner or ship-launched fighter pilot. This seems like it would be pretty fun. I find space Sims get boring though, they tend to get really repetitive. How does elite…
Mission variety is not-so-great, but I haven't taken an official mission in over a year. There is plenty to do if you're self-directed or you participate in community-driven content.
But yeah, ultimately it is a space sim and it can be played without VR (though a significant percentage of players do use VR). It's still by far the most immersive VR game I've ever played. It's also really pretty, especially with some of the shader mods applied (look up some screenshots for an idea).
