Be careful what you wish for, you may end up with Velvet Assassin which I get the impression was not well received.
The thing is those battles you mentioned are all either doomed for the allies failure or are from the perspective of the Nazi side. I'm not saying there will never be a WWII game told from the German perspective, it's just if there is it will either be insultingly sanitised as if it was shown then no one would want to play it. I mean when I play a computer game I want some motivation for my goals. Pleasing the whim of "Zee Furher" is not my idea of good motivation, it only worked for Germans because of:
(a) Peer pressure and patriotims = obviously irrelevant to modern non-germans
(b) Propaganda that the war was necessary, living space, blah blah blah = well it's now obvious that was all bullshit
(c) the cover-up of most of the war crimes, it was easy to ignore them = well now we DO know, who would want to be part of that?
Also, you know that side is ultimately going to lose. But they had the best weapons of the war, though you can just nick em of the dead bodies, I always do in the likes of COD2.
One idea would be the same old battles but open world "sandbox" games like partisans disrupting German supply lines on the Eastern front. And completing other missions like smuggling discarded rockets to the allies from their V2 programme, something that actually happened for Polish resistance.
One idea I had was "what if" scenarios like what if The Battle of Britain had been lost and the Nazis attempted to invade the UK? What if the Japanese had won at the battle of midway, would there be Japanese invasions of the West Coast of the USA. I'd like this if only to emphasise the importance that certain battles are won, that the sacrifice was worth it as defeat would have been so catastrophic.
