Interesting. It seems like only you and maybe few other civs are in prehistoric era. Also tech progression seems to be in disarray now - you are now too slow and AIs are too fast. You are in Prehistoric era, so changes in era infos didn't affect tech progression yet. Immortal has following setup for construction/research discounts (stuff for AI is cheaper than for players): Code: <iAITrainPercent>60</iAITrainPercent> <iAIWorldTrainPercent>60</iAIWorldTrainPercent> <iAIConstructPercent>68</iAIConstructPercent> <iAIWorldConstructPercent>68</iAIWorldConstructPercent> <iAICreatePercent>68</iAICreatePercent> <iAIWorldCreatePercent>68</iAIWorldCreatePercent> <iAIResearchPercent>80</iAIResearchPercent> Techs/buildings/units are 20%/32%/40% cheaper for AI - @Toffer90 you listed buildings and units as having same discount for AI in other thread. Now I'm not sure if units being slightly cheaper than buildings for AI is intended or you forgot to adjust those. I guess choosing between units and buildings is bit of catch-22 now - building buildings helps you to keep up with AI, but then you have less units both to defend and to control properties, that are more aggressive for players on immortal. As for Salamasina leader it seems like someone never got to writing her diplomacy texts. As for civics it was more of general notice - you are balancing civics against each other, so buildings unlocked by civics are important here too. Civic buildings should be balanced against each other too.
