Sekigahara: The Unification of Japan

The battle of Sekigahara, fought in 1600 at a crossroads in Japan, unified that nation under the Tokugawa family for more than 250 years.
Sekigahara allows you to re-contest that war as Ishida Mitsunari, defender of a child heir, or Tokugawa Ieyasu, Japan’s most powerful daimyo (feudal lord).
The campaign lasted only 7 weeks, during which each side improvised an army and a strategy with what forces their allies could provide. Each leader harbored deep doubts as to the loyalty of his units – for good reason. Several daimyo refused to fight; some even turned sides in the midst of battle.
To conquer Japan you must do more than field an army – you must be sure it will follow you into combat. Cultivate the loyalty of your allies and deploy them only when you are confident of their allegiance. Win a battle by gaining a defection from the ranks of your opponent.
Sekigahara is replete with unusual mechanics:

No dice are used

Cards represent loyalty and motivation. Without a matching card, an army will not enter battle.

Allegiance is represented by hand size, which fluctuates each turn.

Battles are a series of deployments, from hidden unit stacks, based on hidden loyalty factors. Loyalty Challenge cards create potential defection events.

Sekigahara is a 3-hour block game based on the Japanese campaign waged in 1600. The 7-week war, fought along Japan’s two major highways and in scattered sieges and backcountry skirmishes, elevated Tokugawa Ieyasu to Shogun and unified Japan for 265 years.
Sekigahara is designed to offer an historically authentic experience within an intuitive game mechanic that can be played in one sitting. Great effort has been taken to preserve a clean game mechanism. (Despite a healthy amount of historical detail, the ruleset is a brief 6 pages.) Chance takes the form of uncertainty and not luck.
