More I think about it, the more I think Russia is optimized (as others have pointed out) for building wide quickly, creating 5-7 population cities over a wide area normally ignored by others, beelining for a desired advanced tech and catching up on other techs and civics in the mid/late game with their trade UA. By then they'd own vast expanses of the map where many valuable strategic resources will be revealed (not to mention artifacts, goodie huts, etc.) Cap off the empire with 2 or 3 specialized cities (culture, science, production) and you're ready for the revolution comrade. A brilliant creation this civ.
