After campaign diplomacy and battle AI, this is my biggest hope that CA will improve over RTW. The battle map sizes I thought were far too small and the terrain became such a non-factor compared to MTW. I missed the varied maps of MTW (remember being the attacker trying to take Austria? there was a challenge!) it seems in RTW their are only a few variants of terrain and they are all sorta boring (im really sick of seeing that same map with the three horizontal hills in the center). Height should be a factor again and holding a hill a good advantage. Plus if the AI can properly defend a hill it should be a little tougher for us human players to rampage across the campaign map.
And I'm done.
