I'm only a new member, but there is a co-operative fantasy roleplaying worldbuilding project currently occuring for the Fantasy Hero System that I'm involved with. It's a generic system able to simulate any genre of fantasy. The project is concerned with the tropes of the genre and making a generic setting and could well do with a look by members of this project.

The thread on the project is here- http://www.herogames.com/forums/showthread.php?t=73066

The wiki set up by the creator of the project (Killer Shrike) is here-
