Based on the historical background of the epic Romance of the Three Kingdoms and the famous Battle of Red Cliffs (Battle of Chibi).
Easily the best real time strategy game ever made, by far its not even close. Level up every single unit in your army from peasants/laborers to 4 different professions of warlords (all with unique attributes and passive abilities). Online multiplayer would of been the best feature of this game but as far as I know there is no way to get it to work, regardless its still an incredible and well balanced game.
Recommended for fans of Warcraft that want a more immersive and in depth experience.
