While I don't really have a problem with the idea of someone playing a child character, I just don't think this game lends itself all that well to the idea. Â I could see someone in the young/mid teens (maybe 14 to 16), but any younger than that seems a bit iffy for a multitude of reasons, several of which have been stated.
I'm not saying you shouldn't play the idea, just that it might not get the reception you are hoping for.
