Take a look at the design of the technology (civilizational progress) progression links, and you can do some history-of-science reflections on it~
Some of the details are quite interesting. For example, the prerequisite for “Communism” is “Scientific Method.” The prerequisite for “Fascism” is “Assembly Line.” Both “Science” and “Democracy” require the “Printing Press.” “Music” requires “Mathematics.” “Calendar” requires “Sailing.” “Combustion” requires “Railroad.” “Monotheism” requires “Masonry” … At first glance these may seem unrelated, but when you think about them carefully they are actually rather subtle, which shows that the designers put a great deal of thought into it. But there are still some things I haven’t quite figured out, such as the connection between monotheism and masonry…
