Yep, XIII, mind moving it?
Umm, I have the game, I play it quite a bit... It is really quite a quality game, I enjoy it...
It looks really good, however; the tech tree becomes problematic as soon as you hit WWI, thenm again at WWII, though not as much.
Problem is, as soon as you hit WWI, all ytour cavalry/bowmen/swordsmen become useless, since the enemy has tanks etc.. planes begin to play a huge role in the game, but you have to build a huge ammount of them, and you quickly run out of gold...
Simply, though, I'd reccomend it, even over Rise of Nations. It is a very good, quality game.
