Hearts of Iron 3
Lots of neat ideas in this game. Though it seems to be more "Micromanage your chain of command and watch hundreds of trade deals spam your screen" than "Fight World War 2." Sadly it's also slow as sin. I barely made it into 1937 (when England had co-opted 3/4ths of the world into the Allies because of the guangxi clique being at war with Japan o_O) as Germany in 5 hours of gameplay. Which consisted of me sitting there staring at the screen as the game slowly ticked through the days of waiting and more waiting and some more waiting after that.
