Alright after playing this mod for a while i gotta say its absolutely amazing. but there's something simple u can to to massively improve this mod.
This mod NEEDS Personalization options for the player. which simply means you gotta add some options in the game rules section to allow people to play the mod the way they want.
Here's some rules that i would love implemented in my game:
Soil fertility off/on
Era system old/new
Plagues off/on/etc
Natural disasters off/on/etc
and finally, soldier refill rate old/new/etc
Amazing mod regardless. hope u keep working on it. good luck.
