This is simply a suggestion, but I would like some storylines with some of the girls so we feel a deeper connection between them and the MC, also interacting with your children, currently you just hear that they're born, name them and presumably never see them again, maybe add some sort of growing up system so you have to solve various disputes or something (could use that random NPC generator thing) you could make it a sex thing or not, don't really care, just some more interpersonal relationship stuff, ya know?
