I've been working on a new map of mine, full of canals, and it just looks so bland with the choice of roads. It'd be great to have roads that are made of cobblestone or some kind rock, rather than just pavement. If you look at most European cities, you notice that a lot have plenty of these roads, and not just for pedestrians. I don't know how much extra work it would be, but I'd really appreciate something like that!
