Reading the comments, I see too many people focused on the art aspect (of course this is OP's articles focus). NFT's applied to art is a bit stupid and makes only nominal sense. NFT art is really just flexing for the rich, because as anyone realizes, right-click save-as is all you need to have the art too, just not the "key" or "ownership proof" to that art.
However when it comes to gameing, its a whole different story. Think of it more like a key to unlock something unique in some digital world.
Want to own the unique special edition sword with rare attributes in the Zelda-verse or the uber lazer in your favorite open world space game? Buy the NFT block chain address to it that says you and only you can have it (check out Phantom Galaxies). Want to own the penthouse apartment in the zuckers-verse? Buy the NFT key that says only you have ownership rights. There are already people buying up digital lots in VR games in development. Want to be a unique character with unique pets in World-of-crypto-craft? Buy the NFT's to unlock these. Want to own a special randomly generated horse in a horse race gambling game? Buy the NFT to unlock, and feed your NFT in with someone else to "breed" a new horse with chances of getting the same rare attributes (this is the concept of D-race). Want to own the rare uber-pokemon in the poke-verse to battle with others (check out Illuvium, same concept)? Buy the NFT to unlock. Sell them if you get bored for more/less money, and the game developer gets a cut!
The gaming and even the gambling application scenarios are enormous. That's why crypto gaming will likely be huge and I myself have invested in it's foundations for the long term (Enjin, Seedify-fund, D-race, etc). It's one of the few applications that makes sense outside of rich snobs flexing.
Tell me I'm wrong.
