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.
They wanted to kill Luke instead of Chewie.
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.
