NFTs can be more than a receipt. It depends on the contract which is programmable and can store state. For example, you can store game state on the chain and generate a svg based on that state which is returned to an external application if they fetch the nft. There are few examples of it I can dig up if you are interested.

  Crazy idea but couldn't a game include the asset but an NFT in a wallet associated to a user account allows them to actually use it?

      Say Call of Duty and Battlefield decide to introduce cross-game weapons. Both games add the weapons as per usual. A user can use one of these weapons if they have the NFT in their wallet (I assume both games have some integration with the wallet). The NFTs are tradeable off-game so there's a CSGO style marketplace - all that matters is if, when you load the game, your wallet has those NFTs. It needn't even be cross-game to be honest, you could do it within the CoD franchise but still allow people to buy and trade class load outs. It could be cosmetic skins for the weapons too - it's not crazy to include limited-availability skins. Why might they do this? Well you turn a loot box system into a collectables system which could drastically increase sales if there's a chance you could not only get a rare drop but make money trading that drop. Do I want this? No, not really. Could it be profitable? Yes. Is it technically feasible? Yes.

        Call of Duty is Activision. Battlefield is EA. What you're proposing is about as likely as Apple adding Windows and Android support for Airdrop and Universal Control.

        The initial complaint was that it's technically impossible, I just gave two random options but even within CoD it's still possible to have tradable items from lootboxes.

        Well for one, it lets you have a store with txs and accounts for free with little code! It’s like a framework for money, and would let you trade items across games so for example I could buy a gun in CoD for a party hat in RuneScape or whatever.

> you can store game state on the chain At great expense, yes. Back in 2017, it cost approximately $76,000 per gigabyte to store data directly on Ethereum: https://ethereum.stackexchange.com/a/896/17413 https://ethereum.stackexchange.com/a/896/17413 Now it's multiples of that (i.e. millions of USD per gigabyte). Of course, that's fine, because Ethereum is not meant to be a data-store, that's where IPFS and FileCoin come in (with their own "proof-of-storage" scheme to sister Bitcoin's world-destroying Proof-of-Work). IPFS should cost less than 1USD per gigabyte while reads are "free" - though I'm unsure how well this will scale over-time. Also, AFAIK, IPFS isn't immutable/append-only storage.
