Hey Steve. Long time no speak. How are you.
Completely agree on the worth, beauty is in the eye of the beholder. Money is only a piece of paper or plastic, but it has value because we have all agreed it does.

You can imporant a machine gun into a swordplay game, but then it would likely represent a sword in that game. Because the NFT is an authenticated digital ID, that ID can be interpreted differently in every game.

If the game is shutdown, you still have the NFT, and that NFT will have historical value and scarcity.
