This bothers me more than a little bit.
I really don't see how horrible it is that shooting games encourage people to buy fancy guns. Those guns do not, in nearly all cases, go on to ever cause harm to a person. Secondly, the sort of people who are buying guns do so because "it is cool, I got this AK-47". The only really "bad" thing about it is that more guns are sold, and honestly that isn't always a bad thing. And it's not like the companies are encouraging it either. They sell guns because they are cool, for sport, for money. They aren't supplying gangsters with weapons. They are supplying fairly rich middle class teenagers/parents. Nearly all armed killings are done with "small time" cheap, crappy, weapons. Nobody goes out with an AK and goes on a shooting rampage. Gun sales aren't going to hurt people. Now, if it were "games encourage lobbies against gun regulations" I could understand the dislike. Also, with Obama in office, gun sales also shoot up. People get scared they are going to get banned. We better start electing pro-gun republicans in that case.
But according to this it may be less of an issue. Strange that the companies questioned wouldn't say 'no, we don't' though...
But the previous link came before this , which seems to contradict their plans in the last link. tl;dr I have no idea.
