Hello! I've asked for help to balance some modifications I made in the XML files, but I don't know how to make a mod, so if someone is interested in make it, I will aprecciate it too much. I really like to play longs plays with no turn limit, and I usually use only 2 mods, one that allow to harvast all resourses and one that make all civics, tech and great people more expensives, without modify production cost. Well, I found the XML files than determinate Global Eras minimun and maximun and minimus turns, and also the ones than determinates how many era points you need to reach a Normal and a Golden Age. The first one are in Expansion1_Eras.XML, and the second one are in Expansion1_GlobalParameters.XML (Notice my ignorance, I thought they were .sql files, no XML, I don't have any idea of this) I just want to have longer eras, more expensive golden and normal ages, and mainly than they are balanced. Thanks! Edit: Also if somebody kwon how to make production cost more expensive but only for the city-states, or if it's possible, they make too much units, considering they don't have to do another thing, except for some builders and districts.
