Same here. I think at certain levels, the game is assumed to model certain aspects of the war, or at least have them “taken care of”. What I mean by that is… you don’t see yourself having to move convoy ships around the board, or make sure you have supply tokens so you can conduct operations, or send out search planes on recon for the enemy… All of these were major aspects of the war, but it becomes too tedious to model every detail. The game would become mind dullingly long and over-complicated. I don’t mean to say that the inclusion of fortification pieces would instantly create all this extra work, but it adds to what is already there. Plus, I would assume that nearly every territory on the board would have some level of fortification. Whether or not they are as large and intensive as the Maginot Line, Seigfried Line or the Atlantic Wall, or as relatively isolated as city defenses… I think they all sort of even out in the end. It is like one of those invisible items that is assumed to be involved and taken care of, without you having direct control over it. Because really, everyone had fortifications, everywhere. But with the advent of real air power, fortifications mattered less in World War II than other weapons and equipment.
