Surprisingly interesting !
As a grand strategy games player I thought this game would be too simple to be interesting. I was wrong. The scope is certainly limited and it's mainly a good entry level game for beginners. But, surprisingly, the game offer challenges and hours of play/replay. I would say it's better that it looks.
I would have rated the game 4 or 5 if it had a difficulty level setting. It's hardly understandable this feature is lacking as it would have been really easy to implement using the existing game mechanics of prestige points. Prestige points can be used to "buy" (request from high command) more divisions or specialized brigades, so why not give more or less starting prestige as a difficulty level ?
