Slower Colonization (Configurable)

Description
Compatible with 1.37.

Decreases the rate (configurable) of colonization for both player and AI countries so that the map is not fully colonized by late game, making your campaign more historically accurate.



Details
Ever feel like colonization is too fast? Want to export your save to Victoria 2/3 for a mega campaign but realize that there's not any land left to colonize? This mod is for you!

This mod reduces the rate of colonization by either 90%, 75%, 50% or 25% (standalone 75% and 50% versions still exist for compatibility) by applying a debuff to the Global Settler Increase modifier of each country. You can change the modifier via a decision, as many times as you'd like mid-campaign, though it can take up to 365 days to take effect. Countries are checked yearly, so there should be virtually no impact on performance.

Due to a limitation of the game, modifiers cannot be dynamic. The solution is using a binary adder system which applies multiple modifiers of different values until the desired amount is reached. See below:



Hovering over the Global Settler Increase in the Stability and Expansion tab shows the binary modifiers added. Note how the negative modifiers add up to half of what the positive modifiers add up to. This can also be verified for the AI by checking a province that they are currently colonizing.



Feedback is appreciated. Let me know if other amounts are desired. In the future, I'm planning on adding options for the rate changing with the game year.

Compatibility
Should be compatible with everything since it does not overwrite any game files.

Can be added and removed mid-campaign since nothing is added to the save file. Also, if you had one of the other two versions, you can substitute those for this one mid-campaign without a problem.

Not ironman compatible.

Acknowledgements
Many thanks to the developer of MEIOU and Taxes which is active and very helpful on r/EU4mods. This mod wouldn't be possible if he hadn't given so many examples over there.

Could you also remove Norway's free colonist? Never made sense they had one given historically they didn't colonize anything after Iceland, which is already established in the game...

NDefines.NCountry.REGULAR_COLONY_GROWTH can slower settler chance.

default slower settler is 25, still too fast.

Actually I looked into the 00_basic_ideas.txt file and it could be possible to switch things around and decrease some bonuses in there. For instance if you put overseas_exploration as the 1st idea, quest_for_the_new_world 2nd that would slow things down a bit. The default date for the colonialism Institution is 1500 - this could be increased to 1525 for example...

In my current game, I set it at -75% and I certainly am impacted by it, but I wonder if the AI is. Perhaps it's what the author mentioned below.

It's 1528 and England has already colonized half of Acadia and all of Newfoundland... Portugal already has a colonial nation vassal that controls all of the Carribean. Spain controls Brazil and is already in South Africa.

How about reworking the exploration idea to remove free colonists and the expansion idea to lock it for everyone until AFTER the Colonization Institution has been adopted by a given country? Protugal and Spain have scripted events that guarantee them explorers and conquistadores, even without it, but at least the others would be stalled. I don't know if it's feasible though.

Maybe you could add a set of triggered modifiers that require base settler % to hit a given interval and have the modifier give a penalty. IE Base settler chance is 10% give a -5% for a total of +5%, its at 20% give it another stacking -5% for a total of +10%. You wouldn't be able to adjust it easy mid mission but it should be possible.

@The Real Shturman the mod works. The problem is that, as I found out while working on the mod, settlers are earned both by the settler "spread" (which is the global settler increase modifier) which ticks every month, plus by the "new settlers" % which gives a bunch of settlers. I don't think there's a way to reduce the % chance for new settlers or decrease how many we get.

1752 almost all provinces are colonized

i don't think this mod works. Yes i can see the negative modifiers in the tooltip, however by 1708 half of Africa, and almost all of Americas are colonized. Yes i made sure to click -90% option multiple times.
什么罐子我说 26 Sep, 2024 @ 10:04am 
can you make it work when the age changes? like during each age the colonizing ability varies, the latter the quicker so should it be more realistic for colonizing(e.g. diseases & tech limitations)

i'm sorry if anyone already asked, but is there a way to only make this affect the ai?
