   Game Writers Guild of the Universe?
  Is there a place like Screen Writers Guild of America where you can post your FULL game stories for both review and rights protection? I would not be suprised if Gamedev.net has this already, but i know you dont want full stories on the forums so im not sure where.   
  I have no problem with people posting their whole stories here for review, but we don't do rights protection.  As far as I know there is no such thing as a game writers' guild.   ;  Copy right protection depends on the country, but it most any orginal works created are automatically protected under copy right law.  So, posting your work here could in theory be used to prove the date that you created the story.
