I played an Ashikaga campaign last night on normal difficulty. By 1611 Ashikaga had only 7 provinces with about 5500 income per year, Mori had all of the provinces to the south and Satomi had all of the provinces to the north. However, a short time later Mori and Satomi went to war. I remained allied to Mori since they would loose that war, and I moved against Satomi just as Mori was disintegrating from attrition with rebellions and re-emergence of Amako. By 1636 I had won 3 battles vs Satomi taking Owai, Mikawa and Mino, and they had stripped their provinces of troops causing numerous rebellions. I'm now in a position to possibly win the game.
