First of all, no, earning nfts isn't anything cool. 2nd, it's not unique, literally any NFT game advertises that they have a player-driven economy but they fail to provide failsafe for instances where the game economy could potentially slide down one-sidedly that it'd have no worth or value anymore.

Honestly think it's just another sht game that couldn't be released in the competitive market so they released it as an nft to have some chance lol.
