Well, I haven't written about my Cossacks & Tartars for a while. I was struggling with the idea of it as a supplement for Lamentations of The Flame Princess or Swords & Wizardry Core Rules. And I've decided to make it compatible with the former(despite my dislike for five saving throws), which is more suitable for game set in the 17th century. So for now I'm working on mounted combat and drinking competition rules. After this I'll move on to the bestiary and rewrite history part.
