Well, I don't have any children, but I didn't have any restrictions on what I watched/played when I was growing up. Don't get me wrong, my parents are awful as human beings, but as parents they were fine. Honestly, if your kid is smart enough they can get around whatever you try to do to stop them, the only difference is that they'll resent you. So, my siblings and I didn't have any restrictions on what we watched (well, okay, for some reason we weren't allowed to watch Cat-Dog, but Silence of the Lambs was just fine), my nieces don't have any restrictions based on what they watch, and I can't think of a single legitimate reason for not allowing my child(ren) to watch/play whatever they like. I don't believe that what media you choose to partake in can really negatively affect you. Unless the child suffers from some form of genuine mental retardation, then the point at which a person can distinguish between, say, a movie and real life, is generally the same age they can actually comprehend what's being shown.
