More governemnts for 1440:
Duchy- It´s costly to make army, and the taxation is regular. medium cost of research.
Kingdom- It´s a regular cost to make army, and a normal taxation. medium/high cost of research and pop. growth is +15%.
County- it´s very costly to make army, but the taxation is high. cheap cost of research. 2.0 points of recruitment, and 1.6 of move.
Empire- It´s very cheap to make army, but the taxation is low. High cost of research . 1.2 points of recruitment and 0.6 move. Pop. growth is +25%
to make a realistic history in these governments, follow my tips:
if you pick a small european country, it´s Duchy
if the civ has only 1 province, can be or a city state, or a county, if u have more than 1 province, u change to duchy.
if you are a expressive civ in your region (e.g. you have more than 10 provinces) you change to kingdom.
You will only be a empire if you enter in great powers list.
