Castles involves the construction of a series of castles on the western coast of England during the 11th century. Castles was quickly followed by an expansion, Castles: The Northern Campaign, and a sequel, Castles II: Siege and Conquest.
The game combines several genres of gameplay including resource management, a text-based multiple-choice storyline and a simple combat mode.
In Castles, the player constructs up to eight castles, one after the other, in various regions in western England and Wales. Each scenario starts in the castle building mode with a flat, empty map of the region. The map has such features as trees and water, but is largely devoid of manageable terrain.
