Oh, and something that really annoyed me right from the start:

As Russia you are able to build the "Winterpalais" in Moscow. I mean everybody knows that the "Winterpalais" is in St Petersburg and that the famous historical building in Moscow is the KREMLIN.
So if they chose to add those historical buildings to the game (Arc de Triomphe for Paris, Hofburg for Vienna etc.) why then come up with such a blunder.
I do not expect a computer game to be 100% historically correct, but some basics I certainly would expect from a game that is set before a historical background and not in gaga land with trolls and orcs.
