That's a little bit ridiculous. My parents had a pretty resonable system when I was a kid- I could play any game, but anything with an 18 rating was banned from the house, and anything with a 15 rating had to be vetted by my parents.
Of course, now that I'm older than 18, I'm allowed whatever games I want.
