My main reason for buying these was to celebrate my new job and have something fun to paint. But I'm not one to collect and paint miniatures without at least hoping to play with them. For one thing, I'm not good enough at painting to justify the expense as a purely artistic hobby. So, I have both short- and long-term gaming plans for this batch of unruly Slavs.
Short term, I plan on accumulating a few more of these miniatures to play Witchfinder General, a skirmish-level game pitting 17th-century pike and shotte soldiers against witches, vampires and other supernatural unpleasantness. The game assumes an English setting (note that the rules share a title with an old Vincent Price movie), but a guy with a musket is a guy with a musket whether he speaks English or Ruthenian, and Eastern Europe is as spooky a setting as any desolate insular moorland.
Long term, I plan on making a Cossack Rebellion army for the upcoming period ruleset by Warlord Games. Ideally, I would also put together a Polish Rzeczpospolita army to provide an appropriate nemesis. And as a bonus, I could combine the two for a Kislev-themed Empire army for Warhammer Fantasy!
