I do like the Lost Sectors. It’s a neat idea to reward exploration. I’m sure there’s quite a few in the game I haven’t discovered yet. I wish they had a checklist of which sectors have them so I could look for them all. But instead every once in a while you get a reward for doing one in a certain sector. And that’s the case whether you already found that one in the past, or not. So instead of exploring new places, it just gets turned into another potential repeatable activity.
