They could do American Civil War, the Prussian-Danish/Austrian/Franco (Bismarck) Wars, and maybe a few Victorian Wars to name but a few. I'd like to see them do all of these in a Kingdoms style release. If CA is going to go strictly with an objective driven scenario release(s) then they'll lose what I thought seperated their work from the other guys. The ability to fight wars on a grand scale...total war. And they'll probably lose me.
