On LGJ and Mark's comments on Nationality: I don't see any problem. When french are conquered by the germans, they remain as french (that's because nationality in the model represent the nation the EG feels
it belongs to and does not indicate the nation where it lives in or the nation it legally belongs to). Their high nationalism (that's in reference to their (french) nationailty) will make'em hate the german rule or any other foreign govt coming in. And they won't rebel against a french govt if it's able to liberate the territory. If the germans are able to retain power over France, as time passes the new generations don't feel nationalistic as their ancestors did, mainly because the new german rule encourages the german nationality (assuming germans apply little or null discrimination, thus encouraging nationality shift). This is simulated through a slowly decrease in Nationalism in french EGs. With enough time, nationalism in french EGs will be so slow that new generations will feel they're germans rather than french and the french EGs will start to disappear.
