I know the internet loves a scapegoat, but it's very, very bad about picking them -- Derek Smart, Uwe Boll, Jack Thompson and the like are all people who are playing everyone like fiddles. They're outrageous characters created specifically to draw attention to themselves. And the Slashdots and Kotakus of the world eat it up...
The thing is, though, that on some level Jack Thompson is absolutely right: video games *are* extremely violent, often simply for the sake of being so violent that people notice how violent they are and give them free press. And that's really dumb.
Yes, we should disagree with Mr. Thompson and the like on principal and defend the fundamental right of video game developers to make such games... but we sure as heck shouldn't be satisfied with things like Grand Theft Auto and Manhunt. We should scold them equally for making games that make us look bad, that abuse the idea of games as art... that skip on clever and sometimes even fun just for the sake of being edgy and extreme.
I think this story, more than anything, should show people that complaints about violent video games aren't being made by religious extremists or self-promoting crazies... the argument is being put forth by intelligent people who happen to believe something different from you.
(We also shouldn't object too strenously to calls for Congress to 'ban' violent video games... because the end result will simply be that the court eventually declares them protected speech. It's just how the process works -- you go through it and you come out much stronger for having suffered the initial 'defeat.')
