作者原文描述：

Partition sucks. This mod adds two new decisions from the start of the game! One lets you add Primogeniture, and the other adds Ultimogeniture. This works for Tribal, Feudal, and Clan governments too!

All AI should switch to either primo or ultimogeniture within the first few months of the game. So, if you want to give yourself a challenge, you could choose to ignore these decisions and stick with partition! (not that you should)

Two notes:
- Evidently not achievement compatible (dang, I know)
- This mod will probably not work with other mods that modify succession laws.

Please report any bugs you find either in a discussion or a comment below! Have fun not agonizing over murdering, disinheriting, and monk-ifying heirs!

If you want a bit of a challenge in order to get primogeniture, check out my other mod here!
