Ok - but how do you know which ones are important? I started a new game, so didn't chase after the one's I've already seen - or some I wasn't really into so I didn't go after those either. So now I don't know how to advance anything, Do I just wander around and get all the GOs I can find, then talk to every single NPC after each one to see if it unlocked something?
This needs to be made much more clear in the game...
