While I'm not going to be "that guy" and demand anyone be fired, the local maps are pretty much useless when navigating in the more vertically designed environments. Not sure why the concept of a 3D map of some sort that you can actually rotated on a few axis should be beyond the Fallout Pip-Boy technology.
On the other hand the fact that you can't pull up your pip-boy and find a way into or out of area does enhance the exploration aspect of the game...
I agree that the local map is pretty much the same, but the problem is that the map designs have changed quite a bit with many multi-level and overlapping areas that make a 2D, top down map fairly useless in terms of pathing assistance.
