I've been going through old 95- issues of SW Insider magazine and the thing that sticks out to me is how they talked about their projects and the fans versus now. Rick McCallum, doing a Prequel update Q&A, regularly says they are making them for fans and that, usually after being asked about FX, says the story comes first. Almost all projects, be it games, books, or whatever, the people involved say the story is first. Then other articles, in particular an interview with Dustin Chin (LucasArts, about Dark Forces 2: Jedi Knight) said basically that fans are loyal and fickle and in most cases know more about SW than they do, so they owe it to them to make a good product. Compared to now where actors and Lucasfilm employees regularly attack fans for real criticism.
On the one hand "the story comes first" is basically an empty catch phrase in filmmaking. A slogan. George Lucas would say it about SW but Michael Bay would say the same thing about 'Transformers.'
On the other hand, modern LFL wouldn't say "the story comes first" that often. They might get around to saying it after they were finished checking off the more important race/gender/orientation issues that actually come first in their minds.
