Before going further, I hope that people understand what I mean by "EU paradigm" and overall historic realism. Unlike EU, Civ spans 4000 years of history and in the standard epic games, takes place on a world map that is totally different than our own Earth map. So obviously lots of historic details and concepts that are appropriate for a game like EU would be totally inappropriate or irrelevant for Civ.
But having said that, there are still lots of broad general overall principles that can be modelled that we would expect even in a Civ-world modelling human (albeit alternate universe) world regardless of historic details. Ideas such as CIv 3's culture, nationality, borders, trade, resources/luxuries, more diplomacy depth, etc were clearly concepts to try to make Civ have an "overall" more historic and realistic feel without adding unnecessary detail that would not flow from an alternative Earth (but which EU implements since it IS a game about real Earth, at least from the starting point).
So when I speak of "EU paradigm", I am only speaking of broad, general concepts that we expect would apply to an alternative-Earth world not the little details that EU implements which tie the game to how history flowed in our real world.
Another way to look at this is to distinguish between "historic realism" and "historic accuracy". EU models both but in a world starting from scratch, there is no such thing as "historic accuracy" since you are creating this history yourself. Nevertheless, even though you are creating this history yourself, certain concepts and principles should apply so that the flow of this "alternative history" is still broadly "realistic" overall.
