@JSS Spoiler : You are having a very nice game there I think! I was found by the AIs on this map, and iirc, I barely got into the trading game with astro on this map. (Or perhaps it was through a chemistry bulb?). That you got trades from early optics stuff is really impressive, good work handling the early expansion! Pacal was such a troll against me on this map that I will rejoyce to see some screenshots of your cannons up against his cities! Regarding your current situation and tech: There was a time where I really liked Mansa. But I dislike him more and more these days... Zara and Mansa are pleased with each other, Mansa has rifling and Zara has Physics+Steel. I would have troubles keeping my cool in that situation. Would drop rifling to Zara (and probably justantin) like a hot rock. Darius and Cathrine are both less advanced, so there is less likelyhood that they will get Rifling (and RP) from any of them. Although it could happen that Justantin gives it away to have Cathrine join the war? Pacal won't get anything from anyone I think, better just keep him stupid, especially since you will roll over him first.
