What do you think of the removal of the straight linear, horizontal settlements like in this screenshot.  The possibility to incline your settlement would match the rough unlinear landscapes of Clonk, and it would make building things easier and provide a more individual look to it. Moving vehicles and moving things in general could become easier for a clever settlement designer, because he wouldn't need an elevator for every obstacle - building paths down or up will do.

Well, "removal" as in the first sentence is the wrong word of course: The player would still be able to build horizontal settlements if he wished to.
