Big potential there I would say. Atari is actually working on that now. I'm sure there will be others too.
I know of a company who is building a silver related Metaverse. They have silver E-Commerce right now and they offer an NFT with your purchase which is offered as an "Certificate of Authenticity." Not a bad idea I'd say.
Other types of gaming could be included as well I suppose.
Disney and many other theme parks using AABB Wallet or Payment Gateway maybe down the road as Penny said...
