As a note, the .DAT files (if you open them with Notepad) have quite a few things that aren't in the game, like decisions over the Ukraine, situations between Romania and Moldavia, various foreign relations issues, etc. It seems the game was rushed, which sucks because the game would have been that much more fun if it hadn't been.
