Morbus Iff, and a cast of thousands (for a very tiny definition of 'thousands'), have released a new GameGrene site, Ghyll. Ghyll is a RPG where players take on the role of a scholar documenting the history of an imaginary world called Ghyll. Based on the concept documented here, I think this is a really cool idea. Hypermedia rules.

>Ghyll is different from previous Lexicons […] because there is no pre-existing world for entries to derive from. We don't know if the world of Ghyll is fantasy, cyberpunk, sci-fi, horror, or all of the above. Ghyll is a blank slate, and will be defined and finessed by our entries. Anything goes until everyone knows.

Update: More on Ghyll from it's other founder, Sean Palmer.
