hi,
well from experience in searching for a fun virtual online game, i figured my top three favourites.
1. Second Life, THE BEST ONLINE VIRTUAL GAME, takes a while to load but it is just a amazing... It is complicated too but u will get used to it AND LOVE IT! its a whole other world.
2. IMVU, it is the best cyberchat game, and it is fun to dress up your avatar with the latest trend clothes. it is quick to download and easy to learn how to play.
3. Frenzoo, This is similar to IMVU but it has less stuff, and is way way easier! Its a fun wayto chat with others from all over the world.
Probably Club Penguin. It is free (unless you want a membership) and good for kids 7-14. you can decorate you igloo, and dress you penguin. Let your child play!
