I'm sure some of you know that Del Rey wanted to do some things in NJO differently than they did. I know that (at least going in), some of these are not popular choices, but in hindsight, what does everyone think? Here are a few of the things I have in mind:
They wanted to use Sith as the enemy.
spoiler:They wanted to kill Luke instead of Chewie.
spoiler:They wanted to kill Jacen, and make Anakin the main hero in the end.
Plus anything else I left off.
Edit: (Just realized that I forgot to say this) The reason that they were unable to do this, is that GL would not allow it.
