The Settlers: Heritage of Kings is a 2005 real-time strategy game. It is the fifth installment of The Settlers series. The game tells the story of a young prince, Dario, who must regain control of his dead father's throne from the evil Mordred. Heritage of Kings breaks from the typical pattern that previous Settlers games had established; while the basic real-time strategy concept of resource micromanagement remains the same, a lot of the gameplay features have changed from those of The Settlers IV, and slightly resemble many of the gameplay aspects of Cossacks: European Wars. Heritage of Kings is also the first Settlers game in 3D.
