The people from Ageod always mention in their game descriptions that their games are 'easy to play and hard to master'. I would actually say they are hard to play and to master, since the interface and game dynamics are nothing alike other strategy games. The worse is gettin used to the 'command chain' system. BUUUUT... if you give the game a chance, it will win your heart. Everything is extremelly well thought out and accurate and history-faithfull. This is a 'grand strategy' game, do not think you will find here any big resource management, or lenthly campaigns and army building and such things. The idea of the game is to put in your hands historical armies in historically accurate reagions, depicting most of all (and this is the unique thing about Ageod's games) a real infraestructure net, which brings you realistic concerns on terms of supply, displacement of your army and the conceivement of an intelligent battle plan. Instead of just advancing and engaging and destroying things, the game gives you real concerns that ruined a good night's sleep of people like a Grant, a Napoleon or a King Frederick.
It is a very adult game, to put it in one word.
