And a tie-in author--no matter how good--is not making her own world. And so you have to wonder about that, wonder about an author who needs to rely on someone else's setting in a genre which is defined by setting.
I don't know that we're relying on it, though. I like to see authors take an existing setting and do something different with it, something I may not have seen before or hadn't considered.
Star Trek, for instance. Forty years and writers are still finding new things to write about. A lot of recent good work in that setting, really good, pushing the boundaries of what's known. The recent TITAN and VANGUARD series, and the recent TOS trilogy by David R George III covering fresh looks at Kirk, Spock, and McCoy. The recent DS9 novels--taking the series and moving it forward in surprising new ways.
And I disagree with the notion that tie-in writers aren't creating their own worlds. Plenty of world-building going on in lots of tie-in novels. They may not be creating a complete setting on their own, but they may well be creating new worlds.
I have three Trek stories published, and another on the way next year. And I have a pile of proposals sitting on the editors's desks to try for more work. And I'm working on original short stories and novels at the same time. I love the Trek setting, so having the chance to write for it is a dream come true. In this case, I can have my cake (writing for a setting I love) and eat it too (writing original fic at the same time). Win win.
The readers who also love the setting get more stories to read. Win for them. The readers who don't care for the setting or who turn their noses up at tie-in work, well, they have the right to their opinion. Just like everyone else. I've read some tie-in work that I've enjoyed more than a lot of the original fiction out there, and I've read some tie-in work that I felt was an embarassment to the ink and paper it's printed with. But, I've also read some lousy original fiction. Tie-in publishing isn't the only segment of publishing with a wide range of quality.
