This sounds like an interesting project. I am also real busy with day job plus MeDem and a host of otther things too but I would have liked to have helped out. I am curious about one thing. The map style is like the Chedian example but the shape - is it completely up for grabs ? Is it a random like map with that style ?

Even if you cant describe the map, can you say what sort of data you have to guide the process. Is it a text description, an outline, a greyscale height map or a piece of artwork to match up to.

We can do what is known as forced perspective to get that 3D look and I can get a script to generate quite a lot of the map then it needs more touching up and embellishing with the text, characters and other non terrain bits of it. The scripting bit I could do quite quickly if that helps you get started. Some people like to make the whole map from scratch tho if they are going to sign up to do it.
