I have had another go at the house rules for adapting FK&P to Eastern Europe. For now we are just looking at the troops needed to refight the battle of Berestechko in 1651, so involving the Polish Lithuanian Commonwealth, Zaporozhian Cossacks and Tatars. When we are happy with these I’ll have a look at Muscovy. The current house rules are here . This is a lot of fun to do. Poor Matt is going to find himself in the gaming equivalent of Groundhog Day before we are satisfied.
