Do you mind to share your CAPX buddy?
Sorry , I'll not share this capx, because I did this in a hurry, and a lot of chunks of events are a shameless copy/paste from other users example capx, and is really a mess.
Now I 'll do it with tilemaps, with extended areas like rivers, forests and so on, and maybe I can turn this into a game.
But I can point you to some tutorials that covers the main concept, and you can achieve something like this.
Build the layout as you would generate a dungeon, but corridors are roads, rooms is terrain for houses, and walls are the place for trees.
But if you have any doubt, ask me please.
