I've been playing by pbem all the major battles and longest campaing in Campaign Waterloo. It's been a pleasure.

We share just one another Napoleonic title: Campaign 1814.
Which of the many campaigns is best or playable for pbem?
Longest campaign La patrie en Danger interests me but is it too long because of so many possible battles?
We play 3-5 turns a week.
Napoleon fought badly outnumbered. Are the different campaigns not so good for pbem because of this?
Bonus Question:
Which Napoleonic title has best campaigns for pbem?
