Seems like your focus is mainly on first-person shooters with a heavy emphasis on high action multiplayer. Okay. Here are some titles you might want to check out:
- Pavlov VR
- After the Fall
- Payday 2 VR
- Dungeons of Eternity
Single player games I think you'd probably enjoy:
- Skyrim VR
- Fallout 4 VR
- No Man's Sky (technically it's mutliplayer, but honestly it always feels like a single player game to me)
- Superhot VR
If you're willing to try something a little different, maybe you'd be interested in these:
- Elite: Dangerous
- Dirt Rally 2.0
- VTOL VR
- Demeo
There are also a lot of games out there that, while they don't officially support VR, have VR mods available that work surprisingly well. It's worth doing some research. If there's a game out there you really like that you think might be cool in VR, chances are someone else has had that same thought and maybe had the skills to do something about it. I'm currently playing Nuclear Option (a combat flight sim) using a VR mod and it is awesome.
