I am pleasantly surprised by the amount of headway this team has made already. I just wanted to make a brief comment/question.
It seems while reading the books, that the vast majority of battlefield units are levied peasants with for armor and farm tools for weapons. It would follow then, that upkeep and recruitment costs for higher tier units such as royal guards and knights should be almost inproportionately larger than levies and militia. This would allow for large, unprofesional armies instead of the ludicrous M2TW 20 stacks-of-gothic-knights burning town by town without any financial burden... Personally, I feel that a really good unit is more coveted when it is precious instead of ordinary.
Anyways, thats my two-cents -- for now at least.
Cheers
