None of that makes any sense. I get what an NFT is. What I want to know is how the mechanics of taking a "sword of fire" from WoW and importing it into RandomNewGame will work without the developer of RandomNewGame specifically programming it in. And if the requirement is that they program in some compatibility with the WoW sword of fire, will they not need to then also program in support for all the billions of existing and infinite yet-to-be-existing items that someone will want to import into the game? You can spin SciFi tales to a different question. I'm asking for specifics on how this ridiculous idea would work.
