For everyone who is bagging the movie industry, and speaking as a (hopefully) aspiring writer, the publishing industry may be in current proportions SOLELY because the movie industry is so interested in making books into films. Like some smart guy said, EVERYTHING begins with an author. Publishing books, on the contrary to popular belief, doesn't make a huge deal of money - what I understood is that most of them attempt to get enough out of it to cover costs of printing books & having editors etc. Of course, you have to think of what will sell, but that's a different story.
Ok, I'm annoyed at all these movies, but I'm also grateful for them, because I think about all those authors that may have had their chance of being published because there are assets for such books.
... I don't know what this had to do with gaming, but I think it's at least slightly on topic!
