Kaiser - I dunno if I fully agree with your synopsis of Stalingrad being the major turning point in the war. Sure the Nazi's didn't win any major battles afterwards, but I think you totally have to consider that could be because they were then fighting a two front war. Fighting on the western front in France against the Allies tends to deplete resources that they could put on the eastern front (in fact, the Nazi's had to pull away resources to go to the western front, from the eastern front if I'm not mistaken).
So yes you could say Stalingrad was a major turning point in the war, but I think in turn because the Allies invaded and gave the Nazi's another front to take care of.
Just my 2 cents worth
But yeah a game on the Russian front would be very interesting
