I want to create a video game and a fictional universe were galactic starships roam and empires are build on a galactic map. I need an economic system or more preciously a worded mathematical formula for estimating a planet's income? Something like base income = population x urbanization rate, strategic resources, number of spaceports, trade goods, shipyards, food capacity, Planetary type..etc I how would I go about building one? Do you have any suggestions? Make sure your entire response is wrapped in JSON format.
