Dunno what to vote. I wouldn't be personally offended, I just think the game would be in bad taste. Either the game glosses over the most beastly and horrible aspects, in which case the game makes light of the atrocities committed by the Nazis. Or, if everything is included in accurate detail, I'm not sure how someone playing the game wouldn't become sick to their stomach.
Well, not every German soldier was stationed at a concentration camp, and not every bullet was fired securing camp boarders. Even tactically the German expansion into Russia is interesting. And without getting into to many politics, the Blitzkrieg was extremely effective; a similar indecent with the 6 (or 7) day war Israel led.
But as is said I am not sure what kind of story can follow those events...tastefully.
However if anyone is interested, from a purely tactical perspective, the Close Combat game does follow largely the Russian and German battles, with a bit of English and US involvement sprinkled in. RTS format, no bases or unit construction, but good war campaign trails. It is also a bit old at this point.
