Video games, to who is responsible?

Ok, I'm a video games players. I'm specially a huge fan of all the games on Playstation/PSP. I'm playing hard games as Gran Theft Auto, so I'm really aware that games are really dangerous because of the addiction, but also, the violence of some. I don't think so that creators are responsible. As soon as they give the informations about who could buy a game, they're responsible. I mean, the parents have to read the box, and choose appropriate games. Normally, at ten years old, a children cannot choose his game by itself. So, it's parents responsabilities to follow instructions. When I was younger, my brother older than me couldn't have some games because of me. He always had to choose games which whom I could play too.
Sooo, that's what I think.
