the idea is simple when nations grow bigger they risk corruption of those who lead it bribes taking and such
so i was thinking why it shouldn't it ably here the more ports the nation have the bigger there corruption percentage
the bigger the percentage the more tax they lose to it daily
lets say for example
a nation with 1 port well have 0% corruption but one with 2 ports well have 1% rate the percentage doubles with every new port to get to 16% for 5 ports
so that would get nation to stick to a few ports and more nation would be able to appear in avonamora
