Free Realms | 9+
Unlike dark, potentially racy massively multiplayer online games (MMos), like World of Warcraft, Free Realms
is an MMO designed with kids in mind. Your character still explores, battles and embarks on quests in a magical, wide-open world, but parental controls (including the ability to limit the on-screen words kids can see) and a refreshing lack of violence help keep things clean.
