I really think these icon are useless to some parents..
Once i saw a kid with his dad in a game store..
It was in singapore, but the dad could have known the icon too..
The kid ask the seller whether he can play god of war ascention on his US ps3..
Not only the seller tell them that he can play it, the dad also happily going to buy it..
I immediately tell the
Child - you can play it, buy you cant use the code to play online. (Dont want to explain about changing region etc)
Dad - (as i am a dad tooo) he should have check te rating of the game, GoWA is the worst title that he want a 10yo to play..
Nudity, gore, beheading -_-
Lastly the seller, i threaten him that i will report to auhority if he sell it to the kid..
The worst thing is in addition to rating icon, there is also a sticker for 21yo only -_-
Edit: i agree that violent game will not lead people to go violent, as when i was young i played a lot of those..
It is all come to parenting who did not supervise their child..
