As part of the twentieth anniversary of Over the Edge, Atlas Games has released the rules for Over the Edge, the Wanton Role-Playing (WaRP) System, under the OGL.

I’ve got a copy of the first edition on my shelf.  It was frankly ‘too weird’ for most of the players I had available at the time, but I liked how it worked and the setting was… unique (definitely part of the weird that kept the Ftr/Wiz and Ftr/Wiz/Thf tree-humpe… elves away… which perhaps may have been part of its attraction to me).
