A few days ago i did a suggestion and now that i think about it, it was so unrealistic and impossible to see in this game,so here is a better one just adding something to a part of the map that feels empty and a few other small things.
My idea is to add a road (Gray part)connecting row 3 and row 4 like the one connecting row 2 and row 1,also replacing that lake between row 4 and row 3 for a small suburbs(yellow part),and finally adding a few secondary dirt roads(Brown part) to the map
I know some people will like it and some will dislike this,but this is just and idea so its hard to see that in game.
