heres an idea :P
How about the really unique idea of parents and video game retailers taking responsibilty for their own actions.
Many a time i've been in a branch of game/gamestation or some local video game retailer and seen games with bbfc ratings on them been sold to children under that age rating, usually with their parents in some other part of the shop waiting for them after giving them the cash for the game.
We dont more ratings, what we need is people to step up and admit when they have done something wrong or made a mistake both by parents and retailers.
Having said that tho, how your brought up counts as well. My parents always took an interest in what i was doing and playing as a child and took great pains to highlight the differences when i was too young to know them, now if i get annoyed at someone or something winds me up i fire up a copy of doom2 and plough through 10 or so levels to calm me down and it goes no further, much cheaper and more effective than any kind of counselling etc etc. Of course parents today dont take such an interest anymore (on the whole) so todays kids cant see why its wrong to kill a real person and why they dont just get right back up again after they've been shot.
Personal responsibility, its something alien to this world.
/note to all aliens watching this world, can i have one ticket off this rock please??
