Seven Kingdoms is a 2D strategy game designed by Trevor Chan, the author of Capitalism. Players choose to play as one of seven human civilizations, each with different stats. They command ordinary people from villages, soldiers recruited in forts, as well as ships and war machines that must be researched first.

Military might is not enough to win the game. Players must plan actions a few steps ahead, trade with other races, build up industry and new villages, and establish diplomatic contacts (spies are included). Cities can be taken over peacefully, for example by making donations to residents. There are two main resources - food and gold. The player has a rate of popularity among his subjects. The game has some unplayable, non-human races - Frythans. They are stronger than men, but have fewer types of units. The lairs in which they reside can be destroyed.
