Many things are difficult to predict, today's NFT looks promising of course many people think that NFT can last for a long time, I don't want to be stuck with predictions like that, as long as this can be profitable then we take advantage of it, but if tomorrow NFT dies then I won't too regret.
The truth is that I do not believe that NFT will die,
For sure it will not die but the hype for a million dollar NFT will be over soon. NFT already established its market and utility in different crypto sector. So there's always a new way to incorporate NFT into new crypto trend. I believe the only sector that it might die are those NFT collectibles that don't have use case at all like cryptopunk.
You're right, just by doing a little analysis of the NFT games we realize that the devs can quickly turn it into a pyramid and make it unsustainable, if you invest little money what you have to aspire to earn is little money after having invested, While in some games for 35USD you can get $ 1k, and who pays that $ 1k? since if you pay from the players who lose it is logical, but not everything is PVP, I think that creating an alternate economy within a game is difficult, even if many oracles are put.
