Since the beginning when it was launched with crypto attributes there, it has indicated that the crypto community has a great potential to make money from there... and those who play are only oriented towards money, not gameplay.... even though I agree with some of the opinions above, where when the gameplay is fun and fair, it gives more attention to players to be addicted to playing games and are willing to spend a lot of money to top up or buy in-game items...
So, I also agree with OP, that game projects to make money in cryptocurrency tend to end in a short time... when it doesn't make money anymore, the game will be abandoned... but some games that are based on fun, they will continue to exist as long as it is still fun...
