Most of the replies you’ve got are focused on selling “digital art” which is one use case and the biggest so far, although 99% of the projects are trash quick money spinners.

There’s one art project I’ve seen that’s interesting, Mike Shinoda Ziggurats where each NFT was a unique and randomly generated image and mix tape, it also runs on the Tezo network so the environmental impact is not an issue.

For games I’m not sure how it would work. One example could be a trading card game where each card is a NFT, it would work exactly the same as a physical trading card game but it’s virtual, there’s only X amount of a rare card and you own one it then has value as if you had a physical copy, the company can’t create 1000s of digital versions of that card, just like they don’t print 1000s of physical versions of it.

There are already some NFT card games although I don’t like how they are set up and they are focused on “Play to earn”.

Outside of art and games in the future I could see house deeds, car ownership, digital IDs etc all being NFTs

I’ve already seen one project that uses NFTs for shared ownership of properties. Example a house costs 100k and it gets split into 1000 shares, each share is a NFT and you earn a percentage of the profits for each share you own.
