So I went ahead and played a lot more turns. I was fully intending on finishing this game but it's harder than I thought So I kill off mehmed with my army of keshiks and then go rebuild mode. I get a huge tech lead. Things are looking great; by turn 200 I had just gotten military tradition and was at 26 cities. I start spamming curriasers and take a few of joao's cities, but not as many as I'd like and I have to end the war as it's becoming too costly. This entire time, sitting bull has been keeping up the tech race and his military. My military score is only 1.2 over him and his army is all up to date. At ~t250 I dow sitting bull to try to prevent him from getting ahead. We have a massive fight but despite me having so many more cities, he's able to withstand pretty well. I'm attaching a save of where I stopped at t275. I literally have 39 cities to his 13, running free speech for extra commerce, building military in almost all cities, and I'm still just barely in the lead. I have no idea how sitting bull's been able to keep up. His army is up to date and while he's a little behind on tech, he's getting the important military ones in time (we both got railroad the same turn) Plan is to get flight->radio and build army in the mean time then attack with bombers.
