I'm not sure of all but I do now a few! :) There is Wolf quest Which is a 3D virtual world in which you can colorize (in natural colors) and play as your very own wolf! on both single player! and multiplayer! Where you can play with others online. There's also Club Penguin in which you can customize and play with your penguin and other people as well! there is I, Predator on AnimalPlanet.com where you can play online and fight against other players in Shark vs Seal, Lion vs Buffalo, and Cheetah vs Antelope. Hope this helped :D (I sometimes play Wolf quest when I'm bored)

A virtual world is an online community. It takes the form of a computer-based simulated environment through which users can interact with one another and use and create objects. The list of virtual worlds for kids would be too large to fit here. There are too many of them these days.
yes
Virtual worlds are NOT bad for kids! The people that interact with your child are probably bad. Some are good, some are bad, but virtual worlds are not bad! Virtual worlds are created by people that want your children, teenagers, and adults to have fun when they are bored, or at any time! Their are many virtual worlds, so don't worry about not finding the one that fits you! Good luck! :) - Sally
