This is a simple file that makes the Population Count for each unit based on the number of people operating that unit. I mean like population count for Infantry is 1, while for Great Bombard is 2, for Mortar its 4 etc. It is more reasonable in my opinion and allows more unit to build.
It also lowers the unit supported for each house while increasing their build limit.
Also the home city cards that lowered mercenary population will lower them to 0.
Its complete and checks every Unit and Cards and so is very nicely balanced.
Copy the files inside zip to (Install Location)/Age of Empires 3/data/ and replace the existing files.
Make sure to backup the files in order to uninstall the mod.
Hope you like it :)
