So, I decided to play an 'inward perfection' playthrough with the new lithoid pack for Stellaris. 200+ years in, and I'm playing ULTRAtall, building habitats everywhere. I somehow got a Tributary (They requested to be a subject, so I was like - fine, okay. It'll protect my western flank by giving me a buffer.)
I have so many stations in my little bit of territory it be a *VERY* nasty sort of thing to try and break in.
