Quoting Adam Passey
Nice, I've been trying to make a barbarian place for a while and haven't been able to get the right system for the bases and paths, do you have any ideas for me???
First I would try to decide what elements you want such as houses, mountains, snow or forest, etc. Try to keep all details on one or 2 sides, and keep them at a single elevation (makes things easier). Each section can then be connected by a bridge of 2, 3,or 4 path squares. You can build at diff elevations and with more detail but it limits connections and can pose challenges. For a theme, the barbarians are said to live in a snowy, rocky, hilly, region possibly with field stone homes or longhouses.
That's my method in a nutshell. Sometimes it takes a while to get it all functional.
