I wonder if it depends on how some people channel it. I have never actually played video games for the same reasons as SF - "hit it until it works" is not really that appealing to me. I have no problem with viewing or "causing" simulated violence, but there has to be some PURPOSE to it - it doesn't feell at all fulfilling to me.
That said, I'm going to throw out a potential parallel and see what you all think of it: what do you think of violent music, for example rap? What effect does listening to lyrical advocacy of violence, murder, drug use, sexual promiscuity, and sometimes hate speech have on people? I think the answer is probably a clear, decisive, "It depends."
For the past four years, I have been a fan of one, and only one, rap artist - Eminem. And it's not one of those, "But Mom, I just like the beat!" things - I have listened to, and been a fan of, his music as a whole, which includes the lyrics as a whole (although there are parts that I dislike strongly). Despite my feminism and my pro-GLBT stance, I (like so many other young people) began in my mid-teen years to identify with Eminem's disaffected attitude, his anger towards being bullied at school, defiance towards the PTB, a parent who didn't care about him, and much more. And so, when I listened to the music, I channeled that anger. For me, it was a way to vent that anger and frustration and aggression and get it out of my system. It honestly began to serve as a form of catharsis when I needed one pretty desperately. It never made me feel MORE angry, save temporarily, it never made me think that violence, drugs, casual and sometimes violent sex, or any of the other acts mentioned were acceptable, and it never even desensitized me to hearing about these things in any other context except that of Eminem's music, not even other artists. In the interests of full honesty, the one effect that it did have is that I became completely comfortable with swearing, and although I don't swear much around other people, I probably would not have picked up the habit at all without listening to this one rap artist.
I wonder if there is a parallel to be drawn there - whether some fans of violent video games are able to use them to vent aggression relatively harmlessly, then put down the controller and walk away from it, without being desensitized to violence in any context other than that of the video game. I think there probably are. For these people, even if it's not the "best" use of their time (whatever that is), it is at least probably not a harmful use.
I recently had the opportunity for the first time to see Eminem (and a lot of other rap artists I couldn't care less about - 50 Cent, Dre, D-12, Obie Trice, and whoever the heck else Em has signed to his label) perform live in San Jose, California, which actually changed my perspective. I guess that I'd always assumed that since rap had no effect on me, that the same was true for other people. But watching the people who were in the HP Pavilion with me, I started to question that. There were definitely a lot of people who were high there, there were people with weapons (the security check was not impressive, to say the least), there were people who were willing to engage in intercourse in the venue itself, and from eavesdropping on conversations, there were simply a lot of very disaffected people who were unemployed and not too interested in finding employment (and yet paid for $85 concert tickets), who had very low self-image, who had been in violent altercations recently or expected to be in a violent altercation that very night, and so on. Now, all that this might demonstrate is that many people who listen to rap music also just happen to be or do all of these things. But, it's also very possible that rap and music generally, possibly in coordination with video games, violent movies, and other forms of entertainment, has had some significant effect on the way they view the world and many of their actions. If the latter is the case, that is far more cause for concern.
Similarly, I wonder whether there is the latter crowd with video games - whether there are people who view violence, carnage, gore, or any of the sex-related or profanity-related peripherals that accompany those games as more acceptable in real life due to the games that they play. I'm not sure if it is possible to tell.
I would hypothesize that video games are at best one factor. Some elements of our society (particularly teenage and young adult males) have learned to glorify violence, and I do not think that's attributable to just one thing. I honestly don't think they have to stop playing video games, and I think that enforcing ID requirements for M-rated games will just put a Bandaid on the wound. These kids have got to be taught, from a much younger age, that there is NOTHING glorious, noble, heroic, or applause-worthy about killing and being killed, whether on a computer or TV screen or in real life. At best, when truly necessary (in the context of NECESSARY war), it is a lesser of two huge evils. And in the videogame context, it is mindless entertainment, which people should not partake of unless they are truly able to disengage it from real life.
