Is there any way to make it possible to raze roads in your own territory?
In case you are wondering, I want this for purely aesthetic reasons, because I find it nearly unbearably ugly if every tile is roaded. So I road only ressources and connect cities. If I conquer some lands however, there are allways roadnets.
I tried removing them via worldbuilder, but that not only also removes everything else on this tile (wich I would accept) but also adjacted rivers.

Can anything be done about this?

just pillage them. if their is something else on the square (farm, mine, cottage, ect...) you will have to pillage that first.

Then we need a "select improvment to Pillage" popup list, SMAC had that I dont see why thye havent included it here.

That is just the problem - you can`t raze roads inside your borders. The Icon just doesn`t show up once only roads are left.
I haven`t tried the hotkey jet, but I think that it is just not possible to raze roads inside your borders - wich is what I want to change.
