I got wondering: when 5E/D&Dnext comes out, is it necessary, from a legal standpoint, for there to be an OGL type license for 3rd parties to produce adventures, settings and the like?
On one hand, if the nomenclature and core systems resemble d20 and older editions, or even OGL newer games, couldn't one simply use the OGL? And on the other hand, even if things are significantly different, aren't game mechanics essentially "open" anyway? As I understand it, they can't be copyrighted, but can they be trademarked?
I believe law and precedent says you can't put "Compatible With D&D" on the cover, but what about, "For Use With The Next Iteration of the World's Greatest FRPG"?
As an aside, isn't this true of any RPG? Assuming one stayed away from trademarks, couldn't you publish adventures or sketchbooks compatible with World of Darkness or Hackmaster Basic or HERO?
