Do you have a prototype of your game already or it's still in the planning mode? That's an ideal game if it's able to integrate with crypto wallets and you can earn and sell your in-game tokens and exchange it to the most accepted or adopted cryptocurrency.

It will be a gamers haven if that integration and feature will come into reality. Your players will be serious about it because they have the means to exchange something valuable that they earn into real-world money through crypto.
