After play the demo I bought the game at a time when I can not get it at my country, there are not downloadable versions and a international shop takes more than a month to be delivered, I get very ansious and the game attends all expectacions. I ever wrote a economics work to college about his economic model - still now one of the best. The optional military module - you can just run automate mode if you can - is a nice idea more games could copy. I reccomend.
