Yes I do. I only have one product now, but within Maidenheim the clash of nations is much more volatile and prevalent than wide-scale conflicts with humanoids or monsters. In fact, this is one of the major themes of the setting. These nations of women fight and war far more among themselves than they do with barbarian invaders or even humanoids, at least for now. Cultures and ideas have been lost, old nations and deities have fallen and have been forgotten, territories and resources are still fought and argued over; kind of like real life.
As far as tech levels, I read in another thread somewhere on this board that clashing tech levels could coexist at the same time, like having a Bronze Age culture still existing near an Iron Age one. Maidenheim combines both of these tech levels simultaneously, with some nations and regions are still using bronzed weapons and armors, while others have already made or are making the transition to iron and steel. This transition stage places them all more or less on the same technological scale.
For the most part, I think the final product has satisifed those who have purchased the setting. Without the conflicting nations, I wouldn't even have taken the time to write and publish Maidenheim in the first place.
