Hm, I wanted to suggest something similar to what someone a page or two earlier suggested, about survival thingy - alas I was thinking of Corruption of Champions 1 (with some changes, since this is not a UI game where you play as fast as you click basically). With a central camp, base or whatever where you just go out and explore and then return there.
But I guess that's more or less what's planned. Only thing I would suggest is making smaller maps, because optimization is a bitch and the demo is already hurting my PC. For comparison, I can run VR in showroom with high settings, but demo is almost unplayable even on medium settings without VR. I mean, it's a fap game, it won't hurt to have smaller maps if it means more people capable of actually enjoying the game (unless you'd make sex scenes in... dunno how to call it, "instanced scenes" so they are loaded separately, based on where it was started in case you had sex in the wild?).
