I believe Malte is correct in thinking that the issue is still too sensitive for it to be treated with objectivity. I know AAFES straight up refused to stock the game here on base. Just imagine a mother's reaction to her child playing as a Taliban member, killing US troops, while every day she's been wringing her hands anxiously, wondering whether or not her deployed spouse will be coming home.
I mean, it's not something I have a problem with personally, being an amateur game designer and probably an apathetic intellectual (though I will continue to deny that), but I understand why it's a sticky issue.
