Hi Daniel,
Sorry, poor forum etiquette. I hadn't checked back in on this thread!
We're a mixed group. Currently we're playing through a 15mm medieval DBA campaign. But we play(or have played) Napoleonics in 6mm, 15mm, and 20mm. WW2 also in several scales, and Cold war stuff. Some of the guys also play fantasy and sci-fi. We often play at one of the chaps houses in Norderstedt, but one player lives in Bad Bramstedt, and we have played there as well.
I think there are also so guys in Kiel, at least I've met a few at past Tactica shows.
Best,
Ed
