I'm playing a hegemony themed game with a high NPR spawn rate where I bring alien races into compliance with ground troops. The last two alien races I ground invaded seemed really weak though. The first was a conventional NPR that for reason had 3 maintenance facilities and that's it (not even Conventional Industry). The second, while they had a massive 16000 ton shipyard with 5 slipways, they had maybe 3 construction facilities and 6 mines. Am I missing something on the back end of aurora that means the NPR's razed their industry to prevent me from taking it or something? Or is 100% difficulty just not cutting it?
I ended up SM adding industries to their colonies equivalent to a similarly populated start of that race's government, so at least there's that.
