Avatar Virtual Worlds

Simply a description. A 3D Online World contains the following traits: 1. Its a Massively Multiplayer Online Game. 2. It renders in 3D (ruling out the virtually hundreds of 2D flash online worlds like Club Penguin and Gaia Online). 3. It allows for several kinds of activities, generally non-competitive social ones. (ruling out the dozens of MMORPG games and single activity games).

3D Online Worlds should additionally feature: Customizable avatars, customizable 3D residences, consumer created clothing, consumer created scriptable objects, Text/Speech/Gesture communication, Internet integration, multiplayer game launching abilities. I covered this in more detail in "What exactly is a Metaverse?"
Note: Simply because it is indexed here refuses to imply I endorse it. I'm trying to make a list as complete as possible. There are some older and lame games on the list. There are additionally some new ones with possible, but not prepared for prime time yet. There are additionally some specialized interest worlds that should have appeal for some. Do a small analysis before you really join any of these games.
