I understand what you mean about the sectors thing but I think it encourages good layout management so you don't have to go back to other sectors unless there's a big problem. Not that I am a master at it or anything, some of my sectors are a right mess and I'm constantly changing them! You can switch to each sector quickly anyway using the sector icon at the bottom left of the HUD. I'm at 4 sectors currently and I'm just checking there's enough resources as it doesn't inform you if something has ran out or is inefficient.
Comparing it to Frostpunk is fair as I really enjoyed that game and I've done it too death, looking forward to Frostpunk 2. Something I have noticed in myself comparing the two games is that I cared more for the characters and people in Frostpunk than I do for the Oinks In Space of Ixion. So much so that I was looking for an option to jettison the useless non-workers out of the nearest EVA to save on resources

. Should have left those darn colonists on the planet when I had the chance...
