A virtual world, also called 3D Metaverse, is a computer-based simulated environment intended for its users to inhabit and interact via avatars. Avatars are usually depicted as textual, two-dimensional, or three-dimensional graphical representations, although other forms are possible(auditory and touch sensations for example). Some, but not all, virtual worlds allow for multiple users.
3DWorlds is a virtual world browser developed for Windows 95/98/Me/NT/2000/XP/2003 Server Personal Computers. It offers users to play games such as chess, soccer, gambling, and trivial pursuit. You may also look at pictures as well as contribute the virtual community by, build your own house, parks, as well as take part in many other in world groups and communities.
3DWorlds also uses VOIP to enable users communicate with other 'Avatars' in world.
