@Izuul Spoiler : Alpha is one of the rare techs that these AIs will always trade. And they probably won't trade stuff like IW/Sailing for a while. So it might be better to go to Currency through Maths (although Maths is pretty useless here aswell). With less land I would even skip maths/currency and go straight for Optics (maybe get Monarchy first). I would say no to Civil Service because it ruins the Astro bulb, even though it has many benefits on a map like this. On IMM maybe you can go for CoL for Confu? (I suppose none of these guys have founded one ) Plus it would help the GP generation for the Astro GS. Not sure how early Confu goes on IMM though. A sure thing is that if you're going for it it has to be through Polytheism, assuming that you plan to bulb Astro, which is probably the most "advanced" move here CKNs? With this much land and such slow techers on your continent cuirs look like a much stronger/safer option to me - especially on IMM, they won't even have Engi by the time you get MT.
