[Suggestion] Child development multi-path system
In another thread, I suggested having offspring rebel against you or do quirky things outside your control. This suggestion is for a system of how that might work (or maybe a less extreme version of it).
You know how some games gives you a "personality test" as part of character creation? Ogre Battle asks you a series of questions about what you value and morality. Other games might have a sort of choose-your-own adventure feel to character creation. Child development could go something like that.
In the first 100 turns after a child is born, the player could receive pop-up messages informing him/her of the child's development and offering choices. If you're harsh on a child and force him to endure strict military training, he might get a stat bonus; but there's a small chance he'll resent you for it and run away or join a rival faction upon reaching adulthood. Other choices might have a mini-quest feel to them, say your child catches fever and requires a rare herb to recover. The choices the player makes would all figure into calculating the child's stats, abilities, and profession.
