The hardest thing I've found when trying to make VR prototypes is to figure out what kind of gameplay is repeatably fun. Whether single or multiplayer, the VR games that succeed either seem to be early titles that got a headstart or those that have replayable content. 
I originally wanted to make a game all about object interactions in VR since I find that to be the most compelling aspect of VR. To just pick something up and discover things about it by throwing it, breaking it or combining it with something else. Reality hit when I realized that any game built around this concept will have too much emphasis on the first playthrough to keep people caring about the game if I ever released into early access.
