There was a recent article in one of the major business publications (which I cannot at the moment locate) talking about how the "Video Game Generation" had potential to be more successful as a result of learning to keep trying and to attack problems from a different angle when you get stuck. Kind of the opposite of what you're saying.
Then there's the old argument of how video games can improve hand eye coordination thereby making you more skilled at work requiring precise control, like
surgery .
This is not to say that I don't see video games causing problems, but I see the problems being more directed at social skills. Specifically, I think that internet/networked games are creating an entire generation of kids that have no concept of good sportsmanship.
I like to play online games. I'm a bit of an MMO addict, but I started out with Quake back in the day and I still enjoy the occasional online frag-fest. The problem I run into, is that I can't find anyone I enjoy playing with anymore. There's no enjoyment to be had in playing with someone who, when victorious, spams you with "h4h4, j00 suxx0rz!! I pwned j00 f4g!" You get the same kind of textual diarrhea when you win, they call you names etc, or they log off in anger.
The anonymity of the internet just seems to being out the worst in these people. They wouldn't act this way if they were in your physical presence. First, they'd quickly find that nobody wanted them around and wouldn't play with them. Second, they'd most likely get their asses kicked if they did act like that. A lack of consequences breeds a lack of respect for proper behavior.
Now, I'm not that old, but "back in my day" we were taught to behave better than this. Everyone likes to win, nobody really likes to lose, but win or lose the contest is most enjoyable when faced with an honorable opponent. Sadly I feel that I am vastly outnumbered by people who have never learned to share my outlook.
