Yeah, I'll admit I haven't played very many either, maybe a dozen. I also prefer longer games so I'm biased towards ports of flatscreen games rather than the usual 5-10 hour native VR games. Still, it has so many elements that are cool in VR that it's going to be tough to beat.
1) There's no one "gimmick"; there are just so many little things you do that feel completely natural with VR controls and not forced.
2) It's so vast, because it was a game just adapted to VR, and they adapted it SO WELL and SO THOROUGHLY!
With the low number of VR players it's going to be a while before there's anything like a native VR Skyrim, so ports are all we've got. And the quality of the adaptation makes a huge difference - games like Fallout 4 and (unmodded) Subnautica could have been stellar in VR but they did a cursory job.
