This is also why the whole Unicorn that NFTs represented WRT "buy an NFT game item and use it across multiple games and even multiple generations of games" wasn't even remotely realistic.
Can you imagine getting multiple developers to agree on a format for the item, what stats will be encompassed within an item, support for rigging, attachment to other items (like a character holding it which may or may not have humanoid hands), agreeing to limit future innovations in their games in order to allow for the item to be used in a future game, etc.?
Hell, you probably can't even get
1 developer to agree on a limited item data format to be supported across multiple present and future generations of games.
How are you going to convince X developer that Y developer's format is the one that should be adopted and then get A/B/C/D/E/etc. developers to also agree?
Considering the revamp that, for example, Turn 10 does with each new generation of Forza Motorsport, just the tires in the game are likely vastly different from one generation to the next as their physics improvements include contact points between the tire and ground, introduction of ambient temperature affecting tires as well as surface (track) temperature affecting tires and then ever increasing complexity of that modeling.
And then lets not even get into whether or not you want say 2005 - 2007 era blocky tires (relative to modern driving games) on a 2022 - 2024 era game.
