Hi all -- since not long after the alpha was released, I've been running a campaign using the rules. Though the characters in my group have been very different from the classic T2K US Army leave-behinds, I have been working from close to the traditional start point: characters stranded on the East side of the Warta, near Łódź.
Since then, the campaign as revolved around local struggles and drama in the vicinity of Łódź, and mostly the city of Bełchatów (which is strategically important for a number of reasons). It is a fun area/moment to adventure in, as almost anything goes. There are stragglers, refugees, Soviet troops, US troops, deserters, and marauders. There is simmering resentment in the local populace. There is the escalating question of "what now" and opinions on the war are up down and in-between.
I've had to learn quite a lot to present a semi-decent picture of this part of the world I have never experienced. I've learned a fair bit of Polish history and culture. I've gradually created a lot of forces and currents that are moving and swirling around the players, and providing hooks for anything from a single mission to a months-long campaign in the area. From here, the players can move on to Warsaw, or Krakow, or all points west... but for now, it's where they are. It seems T2K has traditionally lacked a lot of resources for depicting this immediate area and what to do if you hang around there or get stuck there at all! So I've been revising everything that I've come up with, lessons learned, and getting it all organized for my own sake, but...
Would people be interested in this, as a formal supplement, if I were to sink a bunch of additional effort into it? I believe I should be able to publish it as part of the Free League Workshop, if nothing else (although I haven't seen anything specific to T2K on there yet). I'd anticipate it being somewhere between a "survivor's guide to Belchatow" and something more like the classic 1st edition adventures. Certainly a bit less dense than those in terms of plot and material, but more than enough to feed a campaign from!
