I am in an Immortal game, I am the Aztecs, and I am second in score to Persia who I think is only two techs ahead of me. He has like 50K culture and I am so close to getting Exotic with him, I think I have like 4K tourism with him and GM sitting at his border that I built with 200+ tourism output so that should get me to Exotic, but he will NOT open his borders to me. I only have -12 happiness from him, but I would like to knock that back since I have the GM ready to go. Is it worth a DoW just to sneak my GM in and concert tour him? If I do I can get the Tour in, but would lose the open borders, trade route, and diplomat modifiers and maybe start falling behind as a result.
