Im playing as Germany on a huge map, epic game speed and on emperor difilculty level. I just entered the renaissance age and have been at war with Russia since the early middle age. They are 2-3 times as big as me but my country is protected by a mountain range with only 5 tiles of entry points. I have razed one of their isolated cities and killed countless of their troops. But every time i try to sue for peace they wont even sit down at the table to negotiate and rejects me. I will glady give them some minor compensation to stop the war. Is there someway to handle stubborn AI's??
