What is the mechanism by which your dynasty's heirs will gain their traits and attributes? For example, will it be genetic (e.g. you are good at diplomacy, the wife u select is good at diplomacy, so the child will be good at it too), or will u be able to influence it (e.g. send the child to a military academy to raise military attribute , or instill hatred of nobles in him/herto get a noble hating trait), or will it be a combination of these methods? If u can influence traits throughout the persons lifetime, on the bright side that would make it very rpg-ish and fun, but on the other hand, its somewhat unrealistic, because after people become adults its rather difficult to change their character and mindset.
