I really like Assetto Corsa and Dirt Rally 2.0, although the VR mode for AC is pretty barebones.
rFactor 2, iRacing, and DCS World apparently work really well too, but I haven't really played those.

I think Duel Monsters VR still exists, but you'll have to do some digging to find it.
>co-op RPG
VR Dungeon Knight is probably the closest thing, but I'm not sure how that is these days.

Organ Quarter
Into The Radius
Phasmophobia for co-op ghost busting

I think Skyrim VR is pretty much it, but it's a pretty lazy port that needs mods to make it worth playing, so it's kinda hard to recommend actually spending money on it.
Asgard's Wrath might be worth a look too if you're willing to set up Revive, but it's not really open world.
