This mod brings ideas and policies from Europa Universalis IV to Hearts of Iron IV.

This mod adds 27 idea groups with 7 ideas each as well as 64 policies that you can buy in exchange for Political Power.

The idea groups are split into 3 categories:
  • Administrative: Administrative Ideas, Economic Ideas, Innovativeness Ideas, Communist Ideas, Democratic Ideas, Fascist Ideas, Monarchist Ideas, Minister Ideas, Internal Policy Ideas
  • Diplomatic: Trade Ideas, Diplomatic Ideas, Intervention Ideas, Influence Ideas, Capital Ship Ideas, Submarine Ideas, Carrier Ideas, Espionage Ideas, Resistance Ideas
  • Military: Leadership Ideas, Quality Ideas, Quantity Ideas, Offensive Ideas, Defensive Ideas, Air Combat Ideas, Tank Ideas, Bombing Ideas, Occupation Ideas

Each idea group has at least 5 policies that requires the idea group itself as well as another idea group to be fully unlocked.

All countries have 8 idea group slots which are unlocked by date, from 1937 to 1944 (or 1911 to 1918 if playing with Hearts of Iron IV: The Great War, or 1008 to 1015 if playing with Equestria at War) one per year. A game rule allows to extend it from being able to take 8 idea groups up to 16, the additional ones are as well unlocked yearly. An idea group can be chosen for each slot allowing to unlock its ideas and thus gaining their specific bonuses.
Furthermore, countries have 7 national ideas, 2 traditions and 1 ambition, which are unlocked by completing ideas. To unlock all national ideas and thus gaining the ambition, at least 21 ideas have to be unlocked.

Currently there are 26 unique national idea sets included as well as a generic one.
If you are able to adopt a new national idea set (e.g. Imperial German Ideas), you can switch to them by right-clicking the shield/flag in the idea window and clicking the button to switch national ideas.

This mod can't be used in ver 1.10.2 beta. Specifically, releasing the idea slot only consumes political power and does not reflect any effect.
Perhaps some of the elements added in ver 1.10.1 will be removed in the next update.

im not that good with moding or manual mod installing

@Kürfurst: Ah, yeah. They added something in 1.10 which seemed better and easier for me to create the tooltips for ideas etc, so I changed it to that. But that won't work with 1.9. You can use the direct download link below tho for the 1.9 version. That should work.
Kürfurst Oct 18 @ 8:38pm 
@lemonporn it kinda doesn't work in 1.9.3 version after you updated it. it shows error messages on everything. so i was hoping it to have 1.9.3 version sorry for misunderstanding

@Oberführer Cinnamon: You can download the 1.9 version here (remove the brackets around the dot): http://www.mediafire(.)com/file/d27o58iiy2ouyts/EU4_Style_Ideas_Direct_Download.zip/file

That zip includes the folder and .mod file you have to put into the mod folder. Note that if you have a local version of a mod installed the steam version will not work, so remove it before trying the steam version again.

@Kürfurst: What do you mean? It doesn't require the new DLC. It does require 1.10 tho.
Oberführer Cinnamon Oct 18 @ 9:17am 
Could you release the 1.9.3 version so people can use it if need be?
Kürfurst Oct 18 @ 12:00am 
it seems this mod doesn't work without new dlc?
lemonporn  [author] Oct 13 @ 12:42pm 
@Pelmen: Hm, I see. I won't make a KR specific version of the mod tho, but someone else could make a sub mod technically, just like the OWB one. But I'll see what I can do with the AI ignoring ideas for X years as a game rule.
