I'm playing real word map (no R&F on Immortal) with Aztecs, controlling both Americas and at war with Kongo who controls Africa. Unfortunately I'm behind science around year 1200 and probably will go for Religious victory, I may loose the game regardless. To my surprise they offer peace (lol) and willing to give me a city of them 15 population or a 19 population city state they conquered for ~40GPT (other cities they have is the capital or smaller ones). Would you make that deal? If so, would you keep the city or do you think would be good tactic to free the city state and redeclare liberation war (would be still available to me) or joint war with Egypt as soon as possible again and hope for help of that CS till they offer peace again?
