None of the ones you mentioned want to play in crypto games or play to earn called, and it's only Mir4 and nothing else. Because this game will entertain you and you will not only chase after yourself in this game but happiness while you are playing it.
Although it is up to the players if they want to spend on it or not, there is no problem. But apart from other gamefi or metaverse games, I don't want to play this one anymore.
