But this assumes that occupying Vichy France was not the right thing to do. In fact, it does seem to me that there really WAS no good reason not to do so, and I've never understood why Hitler didn't. I would not be in favor of rules which force you to follow historic courses of action. What's the point? We know who won. The interesting thing, especially in a grand strategic game, is to explore Different courses of action. If there would have been certain negative consequences to occupying Vichy, by all means model them, but don't make the consequences prohibitive (unless they really would have been, but this seems unlikely, since Hitler did, in fact, ultimately do so anyway).
