[Impossible]

I've worked for Oculus and Unity and know a lot of people at Epic and Roblox so I've tried to understand what people mean by Metaverse (outside of directly referencing Snow Crash or Ready Player One). My simplified version is a 3D online game, that has the same number of users and retention as a social network. Almost by definition it has to have user generated content.

Minecraft, Roblox and Fortnite are close in various ways, and many apps have the feature set but are missing the user base.
