I've been agonizing over the fact that no one has been able to create a truly great Conan or Warhammer fantasy game. Age of Conan was pretty fab for the first 20 levels or so, but petered out later on. Warhammer online was, for me at least, a massive disappointment, and none of the others have really set my world ablaze either. Both of these examples have great potential as far as setting and story goes, and it just makes me wonder why no one (to my mind) has succeeded in really utilizing them to their fullest.
What franchises/series/whatevers do you think have great, unrealized potential?
