Gameplay
Seven Kingdoms made departures from the traditional real-time strategy model of "gather resources, build a base and army, and attack" set by other RTS games. The economic model bears more resemblance to a turn-based strategy game than to the traditional "build-workers, and harvest-resources" system in games such as Command & Conquer, StarCraft, and Age of Empires.
The game features an espionage system that allows players to train and control spies individually, who each have a spying skill that increases over time. The player is responsible for catching potential spies in their own kingdom. Inns built within the game allow players to hire mercenaries of various occupations, skill levels, and races. Skilled spies of enemy races are essential to a well-conducted espionage program, and the player can bolster his or her forces by grabbing a skilled fighter or give ones own factories, mines, and towers of science, a boost by hiring a highly skilled professional. For instance, having a skilled Persian general can make capturing and keeping a Persian village much easier.
The diplomacy system within the game is akin to a turn-based game allowing players to offer proposals to another party in which they are able to choose either to accept or reject them. Each kingdom has a reputation and one suffers a penalty for declaring war on a kingdom with a high reputation - making a player's people more likely to rebel and more susceptible to bribery. Diplomatic actions include making war, proposing an alliance or friendship treaty, buying food, exchanging technologies, offering tribute/aid, and forging trade agreements. A ranking system allows all players to gauge the relative military and economic strengths of their allies and enemies, making alliances against the stronger players a natural option.
