Is this actually an elevated map? Or is it just a 2D map with triangles tacked underneath? For example, on the Queenstown map, right center, does King Road go up and down? Or does it curve to the side? Is Hallenstein Street drawn a few pixels further up the y axis because it is higher up the hill? I do like the idea and the aesthetics a lot though.
