I don't think games are a good tool for educating adults about new concepts, they are time-consuming and distracting. You could use them to teach kids, but why would you want to teach kids about Bitcoin in the first place, it's not like they will be using it till they grow up.
Adults play games to relax and have fun, and educational games generally have poor gameplay, so I can't imagine such game being popular.
Games is a good way to educate other people. They are having fun while learning how bitcoin really works. They would fully understand what bitcoin can do if they are enjoying studying about it. Plain text information is much more boring than playing a game while learning so, I do not think that this one is a bad idea at all.
Well, in the past, I've seen some games like a happy farm, harvesting and trading products, we can convert the profits we earn into bitcoin but these games quickly went bankrupt and disappeared when the value of bitcoin skyrocketed and when the bitcoin craze has been flooding in recent years, the idea of a game to educate people about bitcoin is no longer an interesting idea. In order to understand bitcoin, perhaps people should directly visit the websites online, they provide them fully and with the level of knowledge of an average person, we only need a short time to understand all about bitcoin
