A nine-player variant that takes place on map that is limited to the British Isles. Standard map and standard Diplomacy rules, except that every English province is a supply center and England starts out with six armies and no fleets. This variant is designed to be used in conjunction with the standard map. The power's home supply centers include the Capital plus any other supply centers owned by the end of the second year of the game. Supply centers generate currency, which is used to order one's own units or to bribe the units of other powers.
Every player starts out with one home supply center.
Standard Diplomacy rules apply except that a player can build in any owned supply center, not just the home center. Uses the Standard map , but this map uses different colors for all supply centers rather than the standard 7 colors for 7 powers. A five-player variant that uses the standard Diplomacy rules but with a new map which is symmetrical making this ideally a perfectly balanced variant. In this variant, each player has the power to call for a just-completed turn to be rolled back. This is a five-player variant that takes place in the era of ancient Greece and ancient Rome.
