I'm playing at Immortal now and the AI is starting to get religion or cultural pushes that are challenging my finish times when doing science. I really don't have much of a grip on the synergies of the two trees right now. My general idea is to get my luxury/bonuses up and running, then beeline to apprenticeship and industrialization for the factory cheese, picking up writing, currency, and education on the way to keep up science. For Civics I get political philosophy asap, then games and recreation for the collesium, then beeline to exploration for merchant republic, then capitalism, ideology, suffrage and space race. City wise I typically push commercial zones, then industrial, then campuses, putting theaters where campuses don't make sense to keep up the culture points. While this seemed to work at launch, it is not working now. I get to rocketry really earlier compared to the AI by neglecting the bottom half of the tree, but when I have to get Nuclear Fusion and nanotech it takes forever to pick up all the small techs on the bottom half I've neglected, even with the eureka for as many as possible. What are your priorities for science victory, where is the balanced approach for optimal victory times?
