Narvik,
Sorry, I missed your post here.
As to the scope, either version would be essentially strategic. A central Europe setting would just be a bigger map of Germany and peripheral countries. Most of the fighting would be in West Germany and neighboring countries, so the map would segment central Europe into the same number of spaces as the other alternative, but for that reason the game would approach more of an operational level, you’re right.
That said, the polling seems clear that people want the other version, so that may answer that!
:-D
