That's actually fascinating, right now the game seems too easy to me, the only thing that seems to slow it down, for me, is getting the guards to acquire new territory.
I end up having all the brothels and not enough girls to fill them, though I don't ever buy them from the slave market. And I rarely use the catacombs unless some goal requires monster girls.
I'm curious about your Matron problem as well. My matron will take the girls off work when they get tired, but she doesn't always put them back to work.
Though, I do agree with you, there are too many number of things in the game, including girls to manage, at least, for the first play through...
