sims is a game that you can have a virtual house that you can decorate and have a virtual avatar .

Avatar Reality's population is 5.

Avatar Reality was created in 2006.

The Reality of the Virtual was created in 2004.

In my opinion, I think that people use virtual worlds because of the avatars. It's fun to make an avatar and pretend to be someone else for a little while. Virtual worlds are also usual really great visuals. And there's a lot of things to do on virtual worlds. Sometimes there's games, creating avatars, exploring the "world" (once again a visual experience), and chatting and meeting other people who have the same interests as you.

Well, that's one girl's opinion of virtual worlds. :-) Hope that helps!
