@the-general-0 Trust me, you’re going to want to go forward rather than backward. The 2nd edition rules and setup for Europe can be found on the downloads page. There were no changes to the Europe map in the 2nd edtion.
Actually it’s even worse than that if your Canadian considering “Britsh Columbia” and "Yukon Territory merged into “Western Canada”. Of course gameplay is affected little to zilch by this revision.
I say that the next game needs Canada, special neutral rules for Finland, and vichy french rules (and, depending on the time period, poland as well). Why be picky and only make a few improvements? :-D
