This is the current version of the map for my Dwimmermount campaign. Each hex is 5 miles across. As you can see, not a lot of it has been fleshed out just yet, since, aside from the fortress of Muntburg, nearby Dwimmermount, and the City-State of Adamas to the south, the PCs haven't ventured very far into the wider world. As you can see, even geographical features don't have any names yet. I'd been very tempted to name them, but I've thus far resisted, since I decided that it was unnecessary information until such time as the PCs had reason to know the names.
I keep a list of words -- some real, some imaginary -- with me, so that I can create names on the fly as needed, either randomly determining them or choosing one that seems appropriate given the way the campaign is evolving. So far no one has complained about the "lack of detail" and I'm glad of that, since it makes it much easier for me to focus on what's important for actual play rather than world building flights of fancy.
I'm not saying there's anything wrong with world building. I simply know, based on the past, that I can get very obsessive about such things if I let myself do so. For a long time, world building for its own sake was a major pastime for myself and I now realize that, in some cases, it probably prevented me from actually playing. I don't want to repeat such mistakes, so I've kept the world simple for the time being and don't really think much about what it's like outside of our weekly sessions. I'm sure that will inevitably change as time goes on and the campaign expands beyond Dwimmermount itself, but that time hasn't come just yet.
And, yes, the map is based on a section of the Outdoor Survival map. Shock and surprise, I know.
