It seems to me that such a game would be about just as realistic as the cleaned up war the Americans see on TV. No suffering, no civilian victims -- especially no children, no fucked up psychopaths using the rule free area of a war to do what they always wanted to do, no torture, no life-long suffering from handicaps, no PTSD, no being sent in again and again and again until you finally blow your own head off.
Instead it will be full of cynical utilitarian rhetoric and patriotic sugar coating. A fun game for the whole family. Maybe it will even have some religious motives baked into it -- because Jesus loves the war!
