The Wadsworth Constant. The first 30% of anything is filler and can easily be skipped if you REALLY want to sit through every single sidequest dialogue tree. Otherwise, just skip through it all! The storyline is a different story, (hah!) but sidequests are purely filler.
It always goes like this.
NPC: Oh no, a bad thing happened!
Player: Oh no, something bad happened to you!/Sniveling worm!
NPC: My name is X. I do Y for Z, but A came and now I can't do Y and Z will be upset.
Player: I must help you!/Are you offering credits?/You're a weak, pathetic fool.
NPC: If you can do X for me at Y, I'll give you Z!
Player: Elaborate on your plan
NPC: I will now overly explain what is essentially a fetch quest, or something asking you to kill a bunch of crap.
Player: Accept/refuse quest.
Occasionally,
NPC: First go talk to NPC #2.
*trot trot*
NPC #2: I am NPC #2. I'm only here to provide an opposite alignment outcome to this quest, though you essentially do the exact same thing anyway.
Almost EVERY SINGLE sidequest dialogue tree goes like this. The story dialogue trees are usually great because they pertain to you and your character, but all the sidquests are nothing more than NPCs whining because Jabba the Sith Consular pissed on their parade.
Just skip sidequest dialogue, read the Codex entry. Saves you time.
I give Bioware credit for at least attempting to make fetch quests entertaining (even though I do recall them disowning fetch quests, hmm...) but it's simply impossible.
