I appreciate the comment. I think the current kneejerk reaction against violence in video games is uninformed and ideological, but that doesn't mean we should never consider the consequences of technology as it advances.

Is a game of GTA on the PS3 going to turn a rational adult into a criminal? Of course not.

Is there a difference between the developing brain of a child immersed in a simulation, and a grownup playing a game? I don't think that's unreasonable to ask.
