I allways have to smile reading such messages.
In no way a game can learn you how to shoot, use the rifle or carry it.
Real life is much different.
A rifle weighs, you cant keep it shouldered for hours like in a game.
In a game you dont have to take into account the charisterics flight path of a bullet on different distances.
You dont have to look at weather influences, you dont have to worry about breathing.
And if a person would change into a serial killer after playing those games, we should have millions of killers on the road by now
I dont believe a game turns you into a killer......
