I really like the idea that you can breed the best of your slaves, for a future stock of good slaves. I realise that with the current gameplay - waiting for the kid to grow up means youve already passed the point where you would need able slaves.
I like the thought though. Any ideas ?
edit: also, Ive been having 200 slaves pregnant at the same time, but ive yet to see more than 2-3 children. Is this intentional?
