EU5 has bad colonization
the main driver of colonization wasnt the "new world" but rather pop migration due to famine, lack of food, overcrowding, taxation. theres no system showing stability really closest is pop satisfaction.
a lot of countries solved their petty crime with exile, a lot of drunkards and pickpocketers were put on boats to america. instead of the devs trying to nerf popgrowth there should be a gradual expansion of housing in urban areas and if that goes over people will migrate to the new world.
theres already an issue to jumpstart colonies as this system isnt mapped out.
people right now are minmaxxing taxation as theres no real penalty to just tax as much as u can.
if taxation goes to far there should start to be a natural migration to new world.
expelling pops of the wrong culture should have a buff that all mixed cultures have less of a dissatisfaction in new colonies.
colonies should play wide and not tall. most people didnt go there to be crammed in urban areas but rather be homesteaders on the frontier where also you cant tax homesteaders efficiently
