You are a Great teacher.
I'd say just tell the kids the whole truth, that if they tell their parents they might not be alowed to play more, and thus to keep it secret.
Personal I never saw the point in keeping kids from violence and [censured].
It's a lie and crippling, just show them the full uncensured thing and tell them all the full truths, NEVER lie, there is no such thing as blissful ignorance or innocence.
The same thing goes for Santa, having a worldwide conspiracy (including their own very parent and teachers and government and everyone) to keep them in the dark is not very nice no matter what the ignorance is about.
By the way, the teen age group is an artificial construct by society, after puberty one is biological and mental an adult, any difference is put there by the expectations of those around.
And children are far more cappable than peaple thing, just look how fast they lerned the interface, parents are instictivly overprotective not realizing that it probably HARMS the kid far more than it helps them, rant rant rant rant rant rant rant...
Ok, I absolutely don't have kids and never will, I rarely encounter kinds, when I do I cant make sense of them, and they make me nauseous, so maybe I'm not the one to talk about how others should raise theirs, but not leting them play games on the computer because of the content is absolutely ungrounded, DF will never harm them in any way and not letting them play the vanilla version is cruel.
