The probelm is that parents should be banning games in their household - it should not be necessary for the state to do this. Where is individual responsibility in this debate? I agree that young children should not be playing this game, perhaps not even many teenagers...
gotta agree with that... though there are plenty of problems
after all i'm the one in my family enforcing it a lot more since my parents grew up in a time where there weren't ratings anyway (since of the obvious lack of owning visual media at home)
my mother simply can't control it (after all she is happy if my little 15 year old brother goes to school every day not like half a year ago)
on the other side all new consoles and i think even vista offers a central policy system to restrict access to games of certain ratings which should help to lock out younger kids who are totally out of question _but_ that only works if kids are younger
when i was 10 and my sister 13 we did set up the console in the living room and not my parents
also the technical solutions for locking out kids have to improve considerable the next, i'm thinking of some kind of add on device which would look like some some sort of USB hub with additional 5 little USB key ring dongles (colored in the rating colors) which would only have to save a unique value:
when first plugged in, the console should register the keys and don't allow these values to be overwritten by buying an additional such device
it has to to be such a hardware solution because otherwise no parent can outsmart their teenager
but it can't be an built in feature because the teenager would immediately have the control themselves
edit: another thing also about the ratings: not all teenagers are the same: for example there are quite a few games/movies with higher rating here which i don't have a problem with if my brother (15) plays them while on the other side there are some where i have a problem
that said the best ways for making your kid/younger brother/sister not play a game are:
number 1:when the age difference is not big(like with brothers) and they look at what you are playing etc. and they know your a "gamer": say the game is crap
thanks to that trick my brother doesn't play GTA
number 2: the old "i found it totally cool as well" trick.. totally overdone _but_ it still works if the age difference is big enough and you actually have the nerve to do it and you aren't like my mother who thinks Super Monkey Ball is "horrifying" ("those poor little monkeys"... "they scream so horrifying when falling down" .. actual quote .. i'm not making this up)
