Well for a long time I've liked Samurai, cause lets face it, they're cool. And so it was many years ago I had a Clan War army, though that game eventually died (though the minis have recently been brought out again, which haven't stood the test of time well)
Though now there is this
Bushido The Game
And I think it has promise, so frankly may be looking into it when it hits. Hopefully I'll rope some others in as well.
