What is the best 3d avatar game online?

Free Realms is a good online world. Also Xivio. I think the best 3d online game to me would be Fantage!! It's a great 3d website where you can chat with friends, Host your own party, Make friends, Decorate your house, Play games and much much more!! Another great website is Clubpenguin. Where instead of a human it's a penguin other then that it is literally just like Fantage! Play on both.
