Only 6 hours after placing my order, I received an e-mail with a download link and a "key" file (this file has to be placed in the main game folder). Installation was a breeze and without any problems.
I'm not going to pass any type of conclusion about this war game for the time being. The topic is unfamiliar to me and the game is very ambitious. If you are too much into graphics goodies (I heard Napoleon Total War is around the corner), this may not be the game for you. Please take a look at these screen shots I took last night while playing the first tutorial. Make sure to click the images to expand them and see the interface.
