Hi, I made some tests of population growth / approval, here are the results:
Planet population over 1 billion:
1% -> 20% approval = planet loses 10% of its population per turn.
21% -> 40% approval = no population growth.
41% -> 100 % approval = always +200 million people per turn.
Strangely population growth in planets with less than a billion people (wich behave the same as +1 b planets between 1% and 40% approval) seem to have a proportional pop growth depending on the % approval ( from 41% to 100%, the better the approval the greater is pop growth with a maximum of +200 m, and not always +200 m people).
So population stops growing at 40% approval and not 30% as the manual says, and some other posts report it , it does not double at 100 %.
Do you approve?
(the aproval rate i speak of is planetary aproval and not civilisation general aproval)
i'll test it some more later, until then... lets play
