I am undecided on what to do about Italy in the Austerlitz scenario. It seems to me that the French have a poor commander there, and that any move he makes, or even doesn't make (one time I didn't give him any orders at all) results in a defeat at the hands of the Austrians. Gives me the impression that taking Venice is a pipe dream.
I also want to find a way to concentrate on the main action in Bavaria and Austria, and the main function of the Italy campaign would be to keep the Austrians occupied.
I'm currently trying to get my feet wet by playing against the AI, and it's not easy.
