After i got the game, i made some realism improvement to it, so it will feel more realistic playing. What i did is change the recruit cost that required populations. For example: recruiting or forming a party of scouts (3x units) that will require three population points. Also when you get larger size like company 6x, dont worry it will kick in as 6 population points require to form/recruit that unit.
I manage to upload this to nexusmods for Fallen Enchantress (LH), also have Undead DLC as well, but doesnt require it. I find this mod very interesting playing throughout the game, so players will have to becareful what they are doing. Guess it take a day or two for nexusmod to approve my mod so i can uplink it here.
Here the link...
