You have a credibly neutral place to store the items, publicly accessible to any other developer to leverage without having to maintain you're own endpoints and documentation. Baked in royalties. Sounds... much easier than the convoluted solution you propose with standard tech.

Except NFTs don't store the item, they only store a creator-defined URL hypothetically pointing to the item or a hash of it's contents. Also nothing guarantees the royalties if you can just download the item. Nothing in NFTs prevents right-click-save-as.

Steam already has an inventory service, trusted by millions of players to store billions of items. There is already machinery for users to authorise applications to see their inventory. If a game developer wanted to allow use of another game's inventory in their own game, they could already do this.

And users are able to buy and sell the items from each other? Does Steam take a cut?
