step 1) do not allow retailers to sell games that have a rating higher than the age of the buyer. (its supposed to be like this already, but it still happens.)
The problem is that this is illegal and discriminatory. They don't even do this with movies.
step 2) if a parent is buying the game for the kid, TELL THEM ABOUT THE RATING!
That won't work either. The parents are too stupid and apathetic to care about what the rating means. Hence why the kids end up going on killing sprees, with or without video games.
