In 1988, Horde Publications published the rules for Pizza Wars, a wargame for two players designed by James LaFond that was played on top of a pizza.[1] Later the same year, Heathen Thorn Enterprises released an expanded version for 2–7 players titled Pizza Wars Imperium, with artwork by Paul Baker and Richard Thomas. In both games, players fight a wargame where the toppings on a pizza represent the combatants.[2] Qualitygame published an Italian edition with cover art by Paolo Parrucci.[3]
In order to play, 2–7 players collectively order a pizza, each player choosing a different topping. When the pizza arrives, each player takes turns having a group of their toppings attack another group of toppings. Combat is resolved as the number of pieces of attacking topping pieces plus a six-sided die roll versus the number of defending pieces, the higher number winning. The player who wins the combat eats the other group of toppings. The last player to have toppings left is the winner of the game.[3]
