Seven Kingdoms () is a real-time strategy (RTS) video game developed by Trevor Chan of Enlight Software. The game enables players to compete against up to six other kingdoms allowing players to conquer opponents by defeating them in war (with troops or machines), capturing their buildings with spies, or offering opponents money for their kingdom. The Seven Kingdoms series went on to include a sequel, Seven Kingdoms II: The Fryhtan Wars. In 2007, Enlight released a further title in the Seven Kingdoms series, . 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 players can bolster their forces by grabbing a skilled fighter or give one's 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 is akin to a turn-based game, allowing players to offer proposals to another party which they are able to either accept or reject. Each kingdom has a reputation and 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. The original game allows players to choose from seven different cultures to command: Japanese, Chinese, Mayans, Persians, Vikings, Greeks, and Normans. Each culture has its own weapons and fighting styles, and can summon its own "greater being", each with
