I would definitely like to play this kind of scenario and I wholeheartedly agree with many of you observations on how people choose to fight in the last stages of war, it was always one of the things I would ask myself "how did they feel and thought" but on the other hand one of the things I never hope of experiencing.
The main problems that I see are technical, even with the current engine someone must draw the maps (the maps are not tile based) and then would be a question of scale of units, we use battalion sized units where in a city battle many were tank vs tank like battles.
Also about italian campaign, these are old campaigns that we are trying to revive, many authors are no longer active or care.
