I wonder if there's enough of a userbase for VRChat for devs to bother putting together an interactive world advertising their game within it. All I've seen so far is VRKet stuff, and the Grumps world, but nothing specific to VR games.

Eg. A Superhot map, or something from Lone Echo that emulates its 0G movement. This is something Sony tried to do a decade ago with PS Home.
