Hi, I've just heard from EB2, and I am already a great fan ;)
I do not have special knowledge of any kind, but still would like to propose a small work i made when starting discovering the tool.
I understood that you did not ask for any work like this and that it may not fit completely in your mod, but I thought you might be interested in this:
the work there is pretty basic, since it was just some learning example, but since it's started I guess i can finish it. walls and gates are fully functionnal, 30% of the map is made and textures used are vanilla ones, so it can still be a lot more improved. of course it's repetitive, that's to be expected.
so, just to let you know, but I guess there might be a few problems with it (the time frame to have such forts and historical accuracy: i'm no historian, i only took maps on the internet) and then how to implement it: i've got no idea ^^.
