This is the mod I made for iron harvest, mainly to give different factions different characteristics. If you want to use it, you only need to drop all files into config_mp and you can use it. When you place it in the config_MP folder, the value modification only works in skirmishes and multiplayer games.If you want to work in the campaign, please put it in the config folder.In theory, this should work.
Adjust faction characteristics, the Rusviet Union is relatively fast, Saxony is slow
