I agree with Kiya about a YeNo answer. Censorship like everything else can be taken to far; learning not to let it be taken to extremes will be a daily lesson.
Morality must be learned at home. For example, the very first RPG game I played was Balder's Gate. It was extremely hard for me to steal things! I had to force myself to do it initially. Even in <img src="/ubbthreads/images/graemlins/div.gif" alt="" /> I went upstairs first before taking the potions in the room I woke up in. Now take a child who hasn't had a strong background at home learning that stealing is wrong and let them play these games. I'm being half serious and half not serious here, any child I let play my games I make sure I repeatedly say "you know this is a game right? ya da ya da ya da". I mean we do grave desecration! <img src="/ubbthreads/images/graemlins/eek.gif" alt="" /> Seriously, we know it's a game; but, impressionable minds need to be guided and guarded. That's what some of the guides do for us, I bought Grand Turismo 3 for an 11 year old and took it back when I heard you got points for hitting a hooker.
Anyway, there has to be some guides and if the parents don't take the responsibility then society must. We just have to try to not let extremist take over.
