I believe that Runescape isnt targeted towards children but more of a slightly mature audience; in the American gaming rating system I would put RS as rated teen because although the graphics slightly conceal the ominous nature of some parts of the game, there are still skeletons and bloodstains on half of the dungeons in RS. Also, several quests are nowhere near child-friendly material, I would never let my children play Runescape until they were around 14-15. Personally, I was rather disturbed by the plotline of Underground Pass and the Mournings End quests. The Elf quests also had very devious plots. I would never want a child reading an ancient tome about how a witch resurrected some dark lord by throttling a dove and tearing flesh off a corpse.
