We played a good many battles with the various flavours of samurai army when we where playtesting them during development by the ODT.
Not sure if there are write-ups around anymore, I would need to check my archive disks. AFAIR they where always fun to play, and pitching the various flavours against each other will make a small figure collection go a long way (essentialy you get more armies out of one collection, which of course is the same reason to play Green Kislev, Green Bretonians and Green samurai..........)
