There was a very very long and large discussion surrounding family and raising children, it delved into all sorts of things and in particular was the inheritance of skills from parent to child.
From the official side of things, I don’t think there will be children in the game, as @Voxel_pirate mentioned above it’s how you manage them.
I can see a family aspect being modded in most definitely, with all the things you say above, but as for the vanilla game, I’m not sure.
I’ll try and find the discussions bear with me!
Edit: Perfect
The inheritance discussion, as well as a lot of other stuff
