Violent games under attack... again!

When will people realise that games do not directly lead to violent behaviour? And why are video games opponents commenting on something they don't even know about?

The debate reflects a divide in the way people perceive games. Are games harmless, perhaps even cathartic, as many people who grew up playing them believe? Or are they teaching kids to be more aggressive, and in extreme cases, to kill?

To game opponents -- many of whom admit they don't play video games -- it's the latter. They point to new studies that purport to show a stronger link between violent games and aggressive behavior than ever.

Game makers counter that parents are responsible for the games kids play -- and need to understand that games aren't just for kids anymore. Some evidence also exists that kids don't particularly seek out violent games and don't have unfettered access to them.
