I will be filling Europe, yes. It makes for more excitement and intrigue. As for the 'nation listing' its merely there for reference, letting you know what nations are viable. I'm not interested in an Anhalt player or someone in Albania; its a waste of a slot. That entire post will be edited in due time, with unplayed nations removed and names being put beside relevant nations to form a player list.
Player nations will be killed off during this campaign, eventually, depending on how things pan out in the game. If this does not interest you, please re-read the first post!
