this is one of the best games ever
There are alot of options in this game, there are custom battles, campaign, historical battles, and historical campaigns. In the custom battle you get to choose what country to be and how many men you want in your army.
The best part of the game is the campaign, which you can pick between 3 eras of the midieval age, early, high, and late. There are also many factions you can play as and each one has the own advantage anf disadvantage, and even so excusive men.
once you choose the country you want to be than you begin the campaign, now not every campaign is the same, but this makes for a challange.
You can upgrade workshops to get better armys and crush any enemy you want. In the historical battles you replay historic battles that happened during the Middle ages, and in the historical campaign you can follow a war and win it your way.
Overall this game is one of the best i have ever played.
