People seem to gloss over the first example (Project Memento) which I think is a great example where NFTs make sense. It's just a configuration with a fixed value (the coordinates) and a dynamic value you can actually change yourself (the letter). Other apps and games can use the same NFTs to build something different based on the same coordinates. Let's say I build a war game where Project Memento NFTs decide ownership of land on map. The blockchain is an open API and players just need to connect their wallets to my game in order to play. HyperDragons eating CryptoKitties to grow stronger is a good example of one app using NFTs from another. Art NFTs on the other hand are more like digital signatures. It doesn't really matter what is stored in the NFT. What gives it value is the fact that it was minted by X (where X can be an artist or a service). Yeah, you can use IPFS or store a hash but what's the point? You're buying the bragging rights, nothing else.
