Suggestion: Bolesław Chrobry. He was also a Polish king

Mieszko pierwszy!!!!!! niech żyje Polska!!!

I like to play my Poland and this Leader is always fun to play! Ty for ur work!

Sounds like a fun challenge to try and keep the ability going with as many cities as possible.

In fact I remember now that ability was designed to support making Encampments (synergy with civilization ability).

Bonus is applied to Holy Site, Campus, Industrial Zone, Harbor, Commercial Hub and Theater (this is hardcoded).

However the condition considers districts defined in Districts database table that has at least one AdjacencyYieldChanges defined. It may vary for modded games.

I cannot be sure without turning game on. I would say yes for all of them. 100% sure for unmodded aqueduct, dam, encampment, aerodrome and canal.

Will the ability still trigger on a city with an industrial zone even when it has an aqueduct, dam, encampment, water park, government plaza, diplomatic quarter, aerodrome, spaceport, canal, and preserve?

I second that your Mods needs better PR lol

i recommend more screenshots, a better promotional image or however its called, and a better description that says the word poland and such to get a bigger audience

I will pay for the mod for me - New leader of Polish Civilization - Me as the princess of Poland <3

Interested :) ?

It's kind of weird that his bonus works only for cities with one district, while he tries to have maximum number of district in all cities...
