Maybe good will come of this?
A large part of the problem is that parents do not understand / know about / care about games so they'll buy anything for their little 'uns. A clearly explained, unified ratings system similar to those governing video, could potentially help them to understand. Then, if a kid is still playing GTA, then responsibility can be directly attributed to the parent.
And I think it will cease to be an issue in a few years. Games are a big thing now and those of us who have grown up alongside them do understand them.
