Great War at Sea: South Seas Mandate is based on what US Navy planners foresaw as the opening stages of War Plan Orange, the plan for a Pacific naval war against Japan. It is set in the years just after the First World War and features ships planned but never built: the American Design 150 battle cruiser, the Japanese Type X light battlecruiser, the original design for Japan’s Furutaka-class light cruiser and more. Great War at Sea: South Seas Mandate includes 50 die-cut and silky-smooth playing pieces, thirty double-sized “long” ship pieces and 20 standard-sized square ones. There’s a 22x17-inch map (on heavy rigid stock), and a booklet with ten scenarios and the background story of the campaign. -description from publisher's website
