I'm new to widelands and I was suprised by how much the roads and flags actually bloat the overall looks and eyecandy of this game(not that there is much to speak of) I know this game is all about roads and flags are important for the logistics.
But why do the roads have to be so unrealistically straight? It wouldn't hurt to see a tiny bit of wiggling nuances here and there withing the tiles while the little dudes would still go at the same speed without making the journey longer.
The flags also look very uninspiring and dull in your settlement. I wouldn't say no if someone came up with something else to replace the flags. They could be given different shapes and colors, representing your tribe and adding flavor.
I just got a brilliant idea: replace the flags with little houses! This would give you the impression of a real city.
If you find that too extreme, just give the flags new looks.
