When I was looking at yesterday's email, I saw something about a Heiho game in a box. Now this was my first time hearing of this, and admittedly the very first thought to pop up in my mind was dwarves. If we are getting a dwarven game in a box this year then I'm excited.
Googling the term, I find 兵法 (Heihō) or "art of war". More literally "war system"
So I'd guess it's a game for the grand battle scale samurai armies. Perhaps with two each of the ashigaru, samurai, and command sprues, so two players can build a small army each.
@Charles Tottington Almost for sure the samurai.
