I still think a "paper" map (in game) with some kind of clear legend for unpassable elevations, and indication of roads, would be far better than the 3d map. It's cool to look at once or twice, but it's just not useful for anything other than pointing at fast travelable locations.
The game came with a large fold out map, but that's in the box. It's too large and would just get torn and stained and I don't want to have to turn around and mess with it, if I could just hit the map button.
