There's a great endorsement for modern parenthood....
Sarcasm aside, better, more detailed ratings for video games should be considered. Parents should have a way to quickly ascertain the content. In that, I can hear your argument, but I don't believe parents should lightly purchase "Mature" rated video games, movies, or music for 12 year old children.
It is truly bad parenting to be so ignorant of the child's activities, true, however it does seem that they secretly hid content in the game beyond what the box implies.
