Alr I'll think about it

Very good Idea, Can you also possibly make more harsh areas more realistic in terms of development? Ex: Siberia and Sahara having a cap on population growth

done

i think you should describe all the changes in the description per type of terrain with it's impact and percentage, just a suggestion because it seems that it is quite difficult to analyze it individually. and, does this mod also changes the mechanism of growth rate, human development, economy, etc. based on the terrains- for ex. provinces with desert or cold mountains (/any extreme weather terrain) gives low growth rate, however the player could still increase it's growth rate but not as much as non extreme weather terrains.

Leave your opinion about my mod here, in the mighty comment section. I will read your comments and hear what I can change or what is great.
