My opinion on banning video games is: "Why?".
Sure, certain games should be banned *coughmanhunt2cough*, but not all games deserve this fate. Instead of banning video games, why not accurately enforce rating restrictions and piracy prevention laws on the games?
Why should violent games be banned when more violent movies and books are being made? It's not like I'm trained for a rampage by playing eight hours of Tom Clancy games a day, I'm just trained to play eight hours of Tom Clancy games a day.
Take games for what they are. Entertainment, not reality.
