* Hegemon Origin now starts with a 20 year term instead of Status Change.
This change seems pretty weird to me. The idea of a hegemony is that it's... a hegemony. It's not an equal arrangement. Even the description of a hegemony in game was something like "satellite states surrounding a powerful leader". You don't just pass the iron fist every twenty years. It makes some sense if the next president is chosen by challenge instead of on a 20 year rotation, but Status Change seems like the most natural way for leadership of a hegemony to be determined; the state in a position of power won't allow itself to be deposed unless a competing power rises to take its place. This aspect of hegemonies is explicit in the mechanics as well, in everything from the "Secession" and "Join or die" CBs to the new changes: the authoritarian faction demand and locking egalitarian empires out of the Hegemon origin.
I haven't formed a hegemony without using the hegemon origin yet, but if a hegemony created mid-game starts with a 20 year rotating term, I think that's also very unusual.
