That's because penning the movie based on a comic storyline is simply good business. It's a ready-made storyline that has already been tested on an audience (via its comic publication) in such a way that the guys in charge know the story is solid (they know which of their comics was most popular and can use that information to determine which stories get told in movie form). It's also a way of catering to your hardcore fanbase without losing mass-market appeal; the mass-market doesn't care about the comic book story lines one way or the other, but the hardcore enjoy seeing something they've read about recreated on the big screen.
Exactly. And as I said, it's possible they could stop doing that, end the comics and base it solidly on the movies, but D&D has no such alternate base.
The source of your inspiration doesn't necessarily define your business model.
I don't see where that fits into this conversation at all. You've just said that the comics are the base for the movies and it makes a difference for them. I'm saying that the RPG is the base for all the other D&D stuff, and none of it has the creative stream or the hardcore fan base to be the base for the D&D brand. Without the RPG, the D&D brand becomes a generic fantasy term and evaporates.
