Actually, nothing happens. Nothing major I mean.





In my recent game the Oda (yes, they survived!) took it all the way home and declared themselves shogun. I thought this might end the game, but nope, I was free to continue playing without a "Defeat!" screen in sight. All that happens is they become the "Oda Shogunate." And are regarded by the other AI as such.

Something to note: Realm divide is a lot scarier when you're dealing with a Shogunate controlled by an AI clan.
