Alongside our daily coverage of online worlds, WorldsInMotion.biz is also going to be building up a database of the major virtual worlds in our new Online World Atlas.

This virtual world guide, which will become the basis for the forthcoming Game Developer Research papers on virtual worlds, MMOs, and virtual items, includes information on the world, its payment model, key features, useful links, and a brief in-world guide, including exclusive screenshots and analysis on in-world interactions.

We're expecting to add approximately two worlds per week to the Online World Atlas, so check back often to see the latest specifics on a multitude of virtual environments. Currently, we've completed overarching analyses on the following worlds:

Habbo Hotel (Sulake Labs) - June 2007
Club Penguin (New Horizon Interactive) - June 2007

If you have comments, feedback, or ideas on the worlds that you'd like to see profiled in the Online World Atlas next, please contact us via email at editors@worldsinmotion.biz.
