I'm the third strongest civ of five and the second (Genghis) and fourth(Monty) have declared war on me(Mao). After a few bouts where I eliminated their invasion forces, Genghis offers a Peace Treaty (PT) for 10 turns if I give him a tech (Liberalism). I try to negotiate where Genghis would give me a tech but Genghis won't agree. Then I try a ruse asking what would make a Cease Fire work and Genghis wants a city. Finally I try for a straight PT and Genghis won't accept it. When I try to go back to the original offer, it's not possible. Is this because 1) the original offer is marked as refused by the AI and 2) being more powerful than Mao at the moment, the AI will not negotiate? These are my suspisions and I would like to know if anybody else has had this experience. I tried searching for 'peace treaty' but ended up in CIV III. I noticed that Monty, who also got a bloody nose when he tried to invade, hasn't offered a peace treaty; probably because Monty is weaker than Mao. Background: Mao eliminated GW and is alone on the continent. I have tried several ways to keep the research at a high percentage (70-90%) while building up the cities, expanding their borders to cover the entire continent, and trying to generate as many GP as possible. I did not build up as many military units as possible because of the cost so that is why Mao is weaker even though he has twice the territory and is catching up in the techs.
