One of the more difficult games to learn to play well, but it certainly is satisfying.

This is a game where if you enjoy to control every tiny detail of their empire to make it feel personal to you, along with developing government types, gaining favor or angering other leaders, going to war, being able to win multiple types of victories, creating an economy, battling for religious differences or important resources, or just being barbaric and killing your neighbors for the fun of it, this is for you. While the actual battles or their animation may not be the best it still has the best AI I have ever seen in a game. The AI capitalize when you are weak, and will do what it takes to win. The AI is pretty much similar to the online players. Online play is somewhat enjoyable as well. The scenarios allow you to play as America or the British in the American Revolution, and any of the six main powers in the Axis/Allies struggle of North Africa. Also can start a regular game from the Medieval period where you control one of the Crusader countries or Arabia.
Overall, this is a game that has stolen much time of mine, and takes patience to become good at. All the people criticizing it clearly don't appreciate the time it takes to prepare for a war in real life as well as appreciate the fact that this is a turn-based strategy game, not real-time. And it is also one of the most complicated turn based strategy games on the market.
Normally I play RPGs and First Person Shooters where you are actually a character. I have developed a new love for Strategy games from this game, though.
