While we're on this topic I'll add my 2 cents worth. IF anyone really wants to develop some terrains, perhaps overlapping ones could be made , which, together with other folders, such as missions, could be switched by batch files or similar apps, such as the ETO eras were done. IF that switching is possible, then in that case:-
1. Norwegian occupation, convoy attacks, BC raids against German warships, and if possible NJ activity in the Jutland/Kiel area. Map to go from N. England, Scotland and the Shetland Islands, Norway, (as far south to the latitude of Kiel and then as far North from there)
2. A latitude covering only as far South as the Northern Alps and the as far North as possible, Longitude from about Paris to as far East as possible. This would then cover more of the East, maybe up to the partition of Poland. Good for BC and 8th USAAF raids into Hungary, as well as late Nazi-USSR action.
3. The proposed Eastern Front map.
Doesn't MAW cover all the rest?
