results - played as Babylon - 50% science - also had the Adam Smith's Trading Wonder
Communism - income-3415, net gain +840
corruption -446, -67 to unit cost
Republic - income 4277, net gain +237, -1638 to corruption, -556 for unit costs
Monarchy - income 2936, net gain +442, -1032 to corruption, -81 for unit costs
Production for cities farthest away from capital.
Communism - about 20% loss of shields
Republic - about 75% loss with courthouses
Monarchy - about 60% loss with courthouses
I found that many more cities in the Republic government lost a lot of production. Communism also gave me the same 4 turn science techs with more income than republic.
once your cities grow past 12 in Communism you can even lower corruption more with police which results in more income and shields even more.
my favorite governments
1. communism
2. monarchy
3. republic - i dont even research this one anymore
