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.
