After taking down Izzy and George I went after Oda, captured Kagoshima, Tokyo and Kyoto. I was massing impending doom on the doorstep of Osaka and he decided he'd had enough, and surrendered offering me every single thing he's got. His back was broken, but it was still going to take me a lot of turns to capture his remaining cities, so I accepted. Well, he still had eight cities left, so he offered me that. I was doing OK on the happiness front before that.. I had digested around 10 captured cities and was managing to be only around -7 unhappiness, with various things in the works to try and fix that. Now I'm -70. I think I will try.. because.. well, Osaka is the last enemy city left on my entire continent now. But wow, -70 is a lot of unhappiness. I guess I will be fighting off rebels for the next 20 turns. What to do? I'm inclined to say, I'm so far in the hole, it can't get any deeper, annex them all, and start building courthouses. Should I have liberated the city states he owned? It's not like doing that would put me in positive territory, I'd still be in this hole, just probably -40 or -50 instead of -70. No idea. Maybe I should raze them all?
