GTA is an 18 certificate game
As usual a computer game takes the blame for incompetent parents. It's a shame Johnny didn't total their car as then they would have felt the financial pain rather than just a bollocking from the RCMP.
My sister asked me years ago if buying it for her 11 year old was appropriate. I asked her if stealing cars, screwing hookers, dealing drugs and killing people was appropriate for an 11 year old. She said "Obviously not!" so I said "Then why are you asking if an 18 Cert game is appropriate for an 11 year old?"
