I agree with what you say. It is mostly the parnet's fault for buying the games. In mine and Speed's local independant Games Retailer, they always talk to the parents, saying that this game is aimed for 18 year olds and the content is far too mature for your son/daughter. but the parents don't really care, hand over the cash, 2 seconds after recieving the box with the game inside, hand it over to their 10 year old. At least my mum had the "decency" to give them to me outside the shop :p
Anyway, I have not turned out violent or a druggy and Speed canback me up :D I play by the rules (most times as I just said I play 18s ;p) and don't go around stabbing people. I am shocked at the amount of 12 year olds who shout abuse and when we were in year 11 (last year at high school), the amount of year 7s who would use abuse, that they pick up from games, TV, films and peers, is disgusting. We never told year 11s to go .................. when we were in year 7. It all depends on the child themselves, if they're ... as you called it Hybrid ... a "susceptable person watching violence".
I think this new ssytem will make parents think about what they're buying for their "little jonny" but imo 80% of the time it won't make a difference until shops stopping selling their games to parents who it quite obvious that they're going to give the game to their "little jonny" when they get outside the shop. but to be honest, shops are never going to do this ... business is business after all :(
