darthspudius: Items aren't hard to miss. You take your time to look round every area. The important items are VERY easy to spot.
MarkoH01: Agreed but you still have to figure out in which city these items are - so you are back to dialogue searching.
Or just remember what people say?
There aren't THAT many important things to do or find.
Even then, just flying to everywhere you haven't been to yet and examining everything closely will either get you what you need, get you something that will help get you what you need, provide a clue to what you need, or failing that get you something you need for something else. Also you might find some gold on the way to pimp your ride!
