I teach Government and one of the most overlooked parts of history that pretty much no one knows much about (other than the war of 1812) is World War 1. 2 is taught like crazy, but 1 is overlooked. A lot of people just think it was trench warfare, which was a massive part of it, and nothing really else, but there was a lot more to it. Not sure what they are going to do with this game, but the political landscape pre ww1 was one of the, if not the, most interesting political time ever. If they incorporated the Archduke's assassination and the black hand, multiple fronts, gas warfare along with tanks, it was be a good portrayal of this period. It would also be fascinating to allow someone to do a campaign from either side of the conflict.
Really, in ww1, there really wasn't a good side vs. bad side like there was with ww2 and many of the wars after it. The United States sided, financially and through weapon trades, with Britain and France more so because we were stronger economic partners with them then we were with Germany. Many of these countries were just doing what they pledged to do in their individual alliances and pacts with each other (hence the domino). No one was Hitler or Stalin level evil in ww1, which makes it fascinating. It was considered the last gentlemen's war (the gas kind of made people out to be more villains, but that was more towards the end when people were getting distracted).
Anyway, depending on how they go with the story in this game, it could be quite fascinating.
