I'm only allowing Cale to make a mercenary company. This is because, if everyone had a mercenary company, there would be a lot of ways you could kajigger it so that the companies could both act in their best, rational self-interest, and do nothing but serve your own kingdom's interests. This way, there is only one major merc. company, and they thusly have a monopsony, making collaboration as mentioned difficult. Cale also has an understanding with me that I am confiscating them if I feel he is abusing their power. He's the only one who can make a merc. company because he asked first. Sorry, lads.
