Poptropica

Poptropica is this online virtual fantasy website. Kids can create their own avatar from a randomly generated name, and complete challenges. There are currently 12 islands, where kids can solve mysteries, play games, and obtain virtual items. The newest island is Mythology Island, where players go on a mission to obtain objects for the Poptropican Zeus.
Kids can decorate their avatars with the "Costumizer" feature. This enables kids to use various elements of clothing, such as hats, shirts, pants, skirts, hats, hair, etc. to change as they please. As a reward for finishing each island, players get 100 credits, plus a virtual wearable medal. You can use these credits at the Poptropica store, where you can buy costumes and fun features.
There are virtual chat rooms, where players can talk using randomly generated question/answer speech bubbles. The game doesn't make any sounds. Seriously. If you try to listen to it by turning your speakers all the way up, all you'll get is white noise. Your can make your character communicate by clicking on other avatars (non-player generated). Sometimes the character has only one thing to say, but if he/she is influential in the game, then your character will form speech bubbles with phrases. My suggestion is that you go through them top to bottom. That way, you'll know what's going on.
You move your character by clicking. You move your mouse in the direction you want to go, and a transparent blue of green motion arrow will pop up. When you click, the arrow becomes solid and your character moves. They can jump, duck, walk, run, jog, etc. Basic human movement. No, they can't do cartwheels or jumping jacks.
The basic website is free, but you can get previews of new islands if you become a member for $3 a month.
Here's my avatar that I created. I copied the clothes from a girl on the new "Mythology Island."



The very first time you log on, you create an avatar, and then you are transported to an island- any island you choose. There, you do whatever, and when you want to save your game, you click on the blue "SAVE" button in the bottom lefthand corner of the play screen. Here, you choose a name and password, and then it's saved under that name. Every time your log on after that, you press the "Save and Exit" button. It will take you to a page that says "Your Game Has Been Saved", and then you can choose to return to the game, or log off.
This virtual world is very fun and is made for kids ages 6 to 16. It's kid family, doesn't permit sharing of personal information, and is fun and easy for smaller kids, but is harder for older kids. I think it's very fun. So do my brothers, so I think that this site is family-friendly.
Ciao!
