The USA at start can only use 2 I think, researching ideological thought which is supposed to give +1 (so 3?) doesnt actually increae it, how do I determine how mnay I have, how many can I have, and why ingame?
The tooltip at the top indicates the reasons why: you have so many POPs of your primary culture, and are not limited by techs. IIRC it was also mentioned in the developer diary: each 1 million of your primary culture gives one NF point (with a base of 1 point too). So, if you have, say, 3 million Yankee POPs and only 2 NF points, then you'll need to research a technology which expands this maximum number so you can get the full 3 points you would be allowed.The USA at start can only use 2 I think, researching ideological thought which is supposed to give +1 (so 3?) doesnt actually increae it, how do I determine how mnay I have, how many can I have, and why ingame?
