Earthdawn is a game system that is actually the midevil "Shadowrun" world. Original owned by FASA, it was sold to a company called Livingroom Games...
And yeah I mean World of Darkness ...
I would call the game
MVG- Lines Crossed
(MVG= Mage, Vampire, Garou)
So characters could play Vampires, Garou, or Mages :)
The Survivor game... would be like the TV game show with some sexual challenges and of course normal ones, where the players would vote people out :) The winner would not recieve a million dollars of course... just bragging rights :)
