Tootsville
"Tootsville" is a vibrant world of colorful characters. Each child gets his own virtual home, can shop for clothes and furniture, and can eat all the junk food he wants at the local candy store. The virtual games found throughout the world allow your children to earn virtual "peanuts" when playing, which they can trade in for cool virtual prizes. The game is suitable for children of all ages but was designed specifically for 6-14 year olds.
Club Penguin
Presented by Disney, "Club Penguin" offers a virtual world of educational games and platforms for meeting new friends. The site is free to play on but access to some content and features require a monthly membership fee that starts, as of May 2011, at $5.95 a month (with discounts when you pay for several months at a time). The game features filtered chat and live moderators to ensure your child's safety at all times.
SmallWorlds
Players can customize their avatars once they've logged in to "SmallWorlds" for the first time, changing the color and style of hair and clothes. The activities include training pets, hanging out with new friends, shopping for new clothes, and playing interactive games. There are usually thousands of players online at any given time and signing up is fast and free.
