NFT in my opinion is an art that cannot be measured by price and success, but the fact is some NFT games are successful, I have seen many platforms make NFT for up to 500 ETH on OpenSea, but so far, it is only collectible and its value will be increased as many collectors seek.
We've seen NFT develop rapidly, in the Metaverse there are NFTs that you can use for fun things, for example The SandBox, MANA and Hero.
