I sincerely hope that LIBERTALIA will achieve the same results as the examples you gave. Definitely, you need to take a closer look at this project.
I absolutely do not see the difference between this game and a whole bunch of others, why do we need an in-game currency in the form of a token, is it not easier to use Fiat currencies?
The token will be introduced into the gameplay, the game is designed so that it will always be in demand from the players, respectively, the price of this token will gradually grow. The more players, the higher the demand for the token.
