Call of the Kings is a 3d Real Time Strategy game that focuses on Player vs Player combat. Unlike classic RTS games the RTS element is applied to army movement, espionage, diplomacy and estate improvement and not tactical troop movements and resource gathering. You might say that the game style is closer to computer games like Civilization, Heroes of Might and Magic and board games like Stratego and Junta than RTS games like Command and Conquer or Warcraft.
