The Far Seas (1987)

2 player game depicting the hunt for Merchant raiders at the start of World War I. The map shows the whole world. Objective is to sink the German raiders (Allies) or attack convoys and avoid the hunters (Germans). The German player plots his movement, then the British player moves, and then the German player reveals and makes his moves.

This game was later covered by Tactics magazine #49 in Japan. I heard this version used a different developper, probably Japanese designer, Akira Ishikawa.
