Hello guys,
I am nearing the end of game and I am redesigning my Al and designing my Ti stack. But I am not able to find info, how much of these I really need? Is there any point going after higher tiers of space station then 3? Will I be able to harvest asteroids with tier 3 space station? Is the only relevant bonus for higher tiers the increase in space research? (it looks like I can only run 1 lab with space research with tier 3 space station...)
(wiki page I got info from https://wiki.coigame.com/Space)

Thank you all in advance for your tips.
