At first glance NFTs in games seem to make sense. For example take a digital trading card game, might be pretty cool to hold ownership of your cards outside the game and be free to exchange them with other players with no restrictions, right?

But then you have to think a step further: The card is useless without the game. If the game shuts down? Nobody can use the card. If the game decides in two years that the card you own is too powerful and they forbid it from tournament play? Well, wasted money.

So overall you might be able to prove ownership of a "card", but without the context of the game it's meaningless data. And the game has to decide itself what your card means and what it can do. So we're back to simply using a normal database inside the game to hold your cards giving the same benefits (without the headache of NFTs).

The argument that you could use the card or the item in another game is bullshit on top. The other game would have to implement every item, which they simply won't do. So NFTs in the gaming niche are overall bullshit.
