The campaign map is remarkably unaesthetic. The placement of mountains feels too haphazard and lacks believability.
That I mean by this is Calradia's mountain ranges crisscross and run every which way, with different ranges going in every possible direction -even when they are in close proximity to one another. Generally speaking, a mountain range will run along a the direction of a fault-line where two tectonic plates are pushing against one another. A simple example of this is the Andes Mountains on the western edge of South America.
Even places like Turkey -which sits atop multiple fault-lines, sees her mountain ranges follow the rules of geography and exist along those lines.
On the other hand, the geography of Calradia resembles a porcupine or hedgehog, with a labyrinth of random mountains sprawling out in various -often conflicting, directions.
I understand what the devs were going for, they wanted to add choke points and areas to funnel the armies into -in order to increase clashes between the factions. That said, these choke points could have been created in other ways besides placing an endless maze of mountains.
Other terrain-restricting features which could have been used are:
-Impassable old-growth forests
-Impassable swamps/wetlands
-Rivers as boundaries
-Man-made structures/walls (e.g. Hadrian's Wall/Great Wall of China)
These, used in conjunction with logically placed mountain ranges, would make a much more aesthetically pleasing and believable map.
