For me in the 90's it was Civilization. Money in this sort of management video game has a lot in common with managing real money. There are a lot of things you want that cost money, and you don't have enough money for everything, so you have to make tough decisions. Sometimes you should know that you'll need money in the future, so it makes sense to save. Money is really useful, so it's worth working pretty hard if you can make a lot of money. Sometimes you need to do some math to figure out if you have enough money to do something or not, and doing that math will help you make better decisions. Sometimes you can spend money in a risky way to try to make more money, and that might be a good strategy or not depending on the details, so you should dig into the details.
Someone can tell you in a class, "Don't blow your money on stupid stuff", but it doesn't really sink in the way it does when you rush-buy a temple because you're impatient, then you get invaded, and you are kicking yourself that you didn't save enough money to rush-buy some chariots for defense.
