Honestly, I don't think it does, but it makes re-sale of digital media possible. Right now you can't return a crappy game to the shop where you bought it. If you want a refund through Steam or something, there's a limited time. If. you accidentally buy the wrong version of a game, it's a lot of hassle. If you get tired of the game, or just don't really like it, it's basically stuck in your library forever

Attaching the files to NFTs will make these things possible and even easy.

You probably won't even know you're interacting with NFT technology
