Star Fort Concept AKA city of Coevorden

This idea came from pictures I had seen of forts in the age when cannons became king. The sharp angles deflect attacks while providing a lot of surface area for placing defensive cannons. I made a mistake and made it too big though and now I don't think I'll finish it. I had intended it to be a base in which you could build your own city on top of it as if it where a landscape in itself, but as usual I got a bit carried away. I'm just putting up pictures at the moment to spur creativity, but if enough people request a download I will provide the world save. as usual comments and diamonds are appreciated.
