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.
As a gamer, I also liked the idea of this project, because it can really make the game process more interesting and, in some cases, profitable. In any case, all projects that are aimed at integrating cryptocurrencies with other industries deserve attention.
I'm not yet looking into the profitability because if it's working, it will become profitable eventually if it gets players. You have an interesting words there, it's true that integration of cryptos with other certain industries must be taken into attention.
But, wait a minute.
Why is it I'm seeing that it's like only one person and newbie accounts are replying at the same time? @OP was the one to open the idea but there's no answer from him.
