Not having mountains on the Italo-French border is a pretty silly oversight...
I don't see how can be changes in geography justified by testingbut go ahead.
cant you model the map with mountains but not define the region as mountanous?
Now THAT would be confusing.
@King:
OK, I can understand that. For me it is still one more reason to make the map as acurate as possible from the very beginning, but I never made any games.
