I always find it so funny that people are willing to attack videogames for violence that really isn't that extreme.
Even the "Nastiest" examples of my hobby, RE: MANHUNT, MANHUNT 2, aren't that bad compared to the things you hear on the news every single day.
Murders, rapes, wars, serial killers, floods, global warming.
I would rather when I have kids, have to explain
"Dad am I killing people?"
"See, whe you press R1, the Fantasy gun, fires a fantasy bullet, which kills a Fantasy man. This is ALL make-believe"
Compared too
"Dad, why are we sending people to the desert to die on a lie?"
"Well, you see son, people are corrupt and awful and greedy, and think nothing of throwing away the lives of real people like me and you if it gets them a little more money."
If I got too save my kids from the horror and shit of the real world by letting them play a little "Call of Duty" or whatever, Then im going too, reality is SO much worse than anything in any game.
