Activeworlds hosts a Universe of over 500 3D virtual reality worlds. In these worlds you can choose from a vast array of avatars that fit your personality (or your perceived personality - that's half the fun!). You can then move about, play online games, shop and make friends with people from all over the planet. You can even stake claim to a piece of land and build your own virtual home, mansion, estate or castle! If you like to travel, there is plenty to explore.
