The good news (for you), metaverse is merely a concept and can't be realized with today's technology.
so dragons tale was not a thing?
http://www.dragons.tl/games.phpi said back in 2013-14ish that dragons tale could have been expanded into not just gambling using sats but actually let users add more content like uploading images of products they sell which can be seen ingame and users can buy them and message delivery location.(3D ebay)
it is possible and graphic render detail has moved on since the days of dragon tale.
Unless developers can solve the fees and transaction speed, then I can't see Bitcoin being used in a metaverse (assuming that we have the tech to do this with the current state of Bitcoin).
the obvious route..
facebook acts as custodian. like exchange deposits. then you make micropayments within your custodian account offchain.
heck, knowing the plan some devs have. maybe even users can become the exchange 'hubs'
yes it wont be a 'all onchain' thing, because then how will facebook take their cut. facebook dont work for free
