The metaverse is an excellent cash crop. See, for example, the advertising: inside Fortnite there are events consistent in time with what happens in the real world. So the advertisers can get a customized virtual world. And the creative mode gives almost limitless possibilities for customizing costumes, game plots and individual game worlds. That is where the Blockchain technology will be a good help. NFT could provide a means to protect the rights to digital property, virtual real estate and land.
