These include Kingdom (1974) by Lee Schneider and Todd Voros, which was then expanded to Dukedom (1976). Other derivations include King (1978) by James A. Storer, and Santa Paravia en Fiumaccio (1978) by George Blank; Santa Paravia added the concept of city building management to the basic structure of Hamurabi, making it an antecedent to the city-building genre as well as an early strategy game.
