I'd pretty much let my kid play any of these, I'd hope they'd be smart enough to know the difference between reality and fiction. The bible was just as violent as any of these games, so if kids are supposed to be able to handle that, surely they can handle jamming a pen into someone's noggin. (Which, unless it was a metal pen, your pretty much not going to be able to do to someone, the plastic ones would bend in half before it impaled. Don't ask why I know this.
