Atleast Partition doles out lands instead of jobs... there's a book series (Beggar, Thief, Warrior, and King, if you want to read them in game or on an Elder Scrolls Wiki) in Elder Scrolls 5 Skyrim, where the eldest child got the land, the next oldest got the army, the third got the treasury, and the last child got nothing.
Didn't that happen because William the Conqueror kept giving John his brothers' castles?The kid was promised A, B and C, then daddy decided to give A and C to the firstborn, so the kid rebels to get it back. Sound like the norm?
