Virtual Worlds Listing
This list represents only a sampling of the types of virtual worlds, virtual worlds platforms, virtual worlds building tools and related technologies currently available or under development. This field is expanding so rapidly it is impossible to keep up with them all. Links to other detailed lists of different types of virtual worlds are at the bottom of this page.
To a degree these categories are arbitrary, particularly as we are seeing the convergence of virtual worlds, gaming worlds and social networking services. We are also seeing the distinction between virtual worlds and and the real world starting to blur with the development of mirror worlds, augmented reality and mixed reality applications.
