The target player is not an engineer or an economist, but a person on the street that still believes fiat is good and that we are fine with money controlled by the state.
When you decide to create a game, so the target surely the game lovers and a few people that may be interested in it. This is not a bad idea but I assume it won't involve significant numbers of people. Moreover, not all gamers always try a new game, some of them just play with their favorite games and stuck on them. So, how to handle this fact?
That was a good idea too that making a game is an excellent influence on the people, but still, it depends on the target audience. Sometimes when we are creating a game we should need to have a good quality of the game that educate other people or the user and next is to have beta testing to your target users so you can get a lot of information and data what do you need to do to manage your game. Also, it is better if we are aiming to the people who want to learn about the world of cryptocurrency or the bitcoin because some of the users don't mind if that is crypto because they will think it is just a standard coin or gold that need to be wasting in the game. But we don't know that your game is the next future generation that promotes the crypto and you will get a lot of sponsors. If you want to have good feedback too, it is better if you consult a game developer also.
