I do not know if you are familiar with Cities Skylines, however there is this mod called More beautification.
It allows to place props anywhere on the map, and this resulted in people adding their own fences around areas (like big airports, prisons, schools, closed off residential areas etc.), manually designing parks in between avenues, a lot more!
With ability to manually place props in game, we could make a really nice town square, with cobblestone roads, market, hedges, fences, benches, carts, and all other stuff.
