What I love about this game is the attention to detail and quite faithful reproduction of European medieval settings but there is one aspect I think Warhorse (and the rest of you) have overlooked the roads Look at them again and think about who and what uses them?
Humans and horses! So what are there two separate tracks with untrodden grass down the centre like you would see in modern back country roads. You may think it is because of wagons just like cars but what powers the wagons? Horses (and oxen), and horses do not float above the ground like engines on cars. They pull them and walk in the centre so therefore the centre of the roads should be the most muddy and ground down part of the road and should not look like modern roads that cars use
