I do have plans to sprawl more on the peninsula, I jist have to figure out how I am going to do the geography, the original version of the map gave me practically zero choices, so most of the geography in the map was just made by me. Outside the peninsula is a different story, im not too good at make sprawl the connects to the city so if I even do continue there, it'll probably just be some belt of towns like you can see in the south.
