This is why the only games I was allowed to play as a child were "educational" games on a Macintosh. Heck, I even had a special console called the "Socrates" for playing educational games.
You bet your bottom I'll do the same to my children. No games, period--until they're of an age to appreciate gaming for what it is. I've seen too many products of the so-called "Nintendo Generation" to approve of gaming for youngsters wholeheartedly.
And yes, I pay attention to the ratings on the box, even when selecting games for myself.
