Mr Postman kindly dropped off a package today which I have been eagerly awaiting for some time. It contained the block wargame Sekigahara: The Unification of Japan from GMT games. Sekigahara is a three-hour, low-complexity block wargame based on Tokugawa's campaign in 1600 that would unify Japan for over 250 years. The game contains elements which I love in a boardgame, hidden movement and card play.
