Would be cool if the map consisted of a bunch of small regions that could be designated farm, forest, heavy forest, river, mountain, town, or city. Regions would be formed by gathering these regions under one lord. This way regions wouldn't be rigid. Through conquests, or same realm lords competing for land would change regions shape. Bold lords could try to make a very large size region, but penalty for size would start happening. Also a lord would be able to change the function of small region with exception of heavy forest, river, and mountain. If a lord wanted to increase the population of his region he could change farm land into town districts, and then need to wait for it to be populated. Similarly a lord could try to create a city, by changing town regions to city. If to many lords try to make large cities and towns then there will be a food deficit on the continent, and lords choosing to have massive farm land could make huge profit. Forests could be cut down and turned into farms, but if production stayed to low for to long then it would change back to forest. Anther thing is lords could plan on the placement of roads, walls, and bridges through the small regions making their land very customizable, and the continent always changing.
