I prefer to take my countries piece by piece. I want to gain a foothold and slowly take cities and provinces as my forces creep forwards. Getting the entire of France in one turn seems kind of... empty. Like I didn't have to work very hard at all for it.

Mods will be fixing this of course, adding provinces back into countries like France which lost them. I'll probably enjoy the game enough to last until someone comes along and makes the map truly epic.
