Features that can be added to a map. Auto-translated

1) The player receives a large amount of money at the beginning, for example, 1,000,000. But every day, a certain amount is deducted, for example, 10,000, and resources are also taken away (although they don't have to be). The gameplay logic will be significantly different from the traditional one. (This feature can be added to almost any map.) 2) Take out a loan. In an impassable location, there is a hero who cannot be lost. He has several events there, through which he can receive money, but in return, he incurs debt. (This can be added to many maps.) 3) Free artifact giveaways. There is a certain point where a free artifact is given an unlimited number of times. (Both to the player and possibly to computer characters.) (This can be added to many maps.)

Could you please tell me how to add these features to maps?
