a PvP/solo vr game, where one person gets to have fun and decorate their home however they like, with a budget of course, and you have until nightfall to do it, in which you have to go to bed, and get all rested.
Except on random nights (so maybe you get a few days between), monsters start popping up, and can either sneak in, or just make the largest fuss, attempting to kill the MC, and based around how you designed your home, you have to defend yourself in near darkness. so you have a broom, or a bat, or something for a weapon you can use as a slight long range melee, or maybe you have a knife collection right next to the bed. Blanket shield.
Add in various stages where you get "studio apartment" "2 bedroom apartment" "house" "2 story house", and shit like that, so you have to account for space, and the like.
The PvP would, of course, be other people playing the monsters, but you could still solo with AIs.
Anybody want concept art, ask/reblog, and I'll post it the @squid--inc--writes
Or mak your own, have fun with it.
