Ummm, well doing a World War II game from the perspective of the Germans would be easy, including the whole "one man army" thing. The thing is that they won a lot of battles and also came within milimeters of winning the war.
The problem is that it would play havoc with some peoples political perception of history. History tells us most Nazi victories were massacres (we, the winners wrote the history books after all) and a lot of their victories are re-interpeted. For example someone mentions the Nazi invasion of France and the perception of how that went down. In reality France was very pro-Nazi and while there was a resistance it was nothing like history chooses to remember it due to the loss of the Nazis. The Nazis would "accuratly" be portrayed as being in control against trivial resistance until outside intervention, and ultimatly fighting alongside the majority of French to stop the resistance and ultimatly meeting failure with the rest of the war. That would however not be a good theater for a lot of reasons, among them the simple fact that it would cause a lot of people to freak out.
In such a shooter you could pretty much have the Nazi hero act like "Rambo" and be there for every battle the Reich won, with the ultimate point that in the end you can win battles but still lose the war overall. The paticular hero could of course go into hiding with a fortune of art and gold, perhaps moving to live out his days in South America with other Nazi veterans.
Truthfully though the contreversy of such a thing would kill it before it ever got made. In the end it would be considered offensive and hateful, as well as calling a lot of people liars(which would be true). Basically to do it, you'd have to remove a lot of remaining propaganda from the war. The Nazis would still be "bad" but nowhere near as bad as they are portrayed, and I think a lot of people would be very uncomfortable with how many things they (and Hitler) were right about when it comes to things like Economics. Hitler was an international man of the year for a reason.
You could also do "Fantasy World War II" from the other perspective as well, though again some might find it offensive. Basically people like to portray Hitler's occult intrests as him being like a Satan/Cthulu worshipping cult leader. You don't have to portray things that way, you CAN portray his guys as more or less a positive force, protecting humanity from monsters and supernatural threats at the same time as they bring power to the Reich. What's more you could also focus on touchy subjects like all of the stolen artworks, and christian artifacts he recovered from Synagogues and the collections of wealthy Jews (some museum collections are heavily criticized because of this... in some cases having faced 'we stole it first' arguements from Jewish families demanding the return of paintings and such).
One "legend" about World War II was that some of Hitler's strategic mistakes were made due to advice from his Astrologer. Imagine using that as a literal truth for a fantasy game, but in this case Hitler is given the choice of either saving the world, or following the advice of his astrologer and ruling over it's post apocolyptic ashes, and he sacrificed his bid for world domination to save everyone, including those he hated. People would utterly freak if someone did that in a game, but the potential for the story DOES exist as does the heroic portrayal (through fantasy or otherwise) of any other doomed battle.
I guess my point is that it can be done, but we're not ready for it. Today Hitler and the Nazis are not portrayed in any realistic light, even in a purely historical sense. They were bad guys (have no doubts) BUT we portray them as a group of super villains, and tend to forget that they almost conquered the world, and that wouldn't have been accomplished by a handfull of psychos in uniforms. Simply put he convinced a massive portion of the world population he was right. The biggest cautionary tale in Hitler is that even a charismatic and well loved man who is right about 95% of what he says, still needs to be watched critically for how insane the OTHER 5% of what he believes is. The videos of Hitler ranting do no justice to how charismatic the man was, nor do you typically hear much about what he did to become Man Of The Year.
It's very, very easy to portray everything in an entirely differant light, especially when you omit our own propaganda.
As I said though, the world isn't ready for it. Plus I admit I sort of fear if someone was to develop it, it would be a group of Neo-Nazis who would use it as a reverse propaganda piece, rather than simply presenting things from a differant, more gray, perspective.
anzers games both had German (or, in the case of the second, Axis, as you also got Italian troops and materiel) campaigns, though the campaign in the first game ends at Stalingrad and I never finished the second game.
