Steve added in a small possibility for multiple NPR's of the same race to spawn on a single planet a couple versions back. It should be possible, in theory, to get 3-4 NPR's in one system, if there are multiple habitable planets and one or both get multiple NPR's. In terms of relations, I think that there is a timer during which they will not suffer maluses, though I'm not sure if this is global (from the start of the game) or local (from when they were created).
Is that affected by the truce timer setting at the game start? I started without any pre-made NPRs, so I had it set to 0, figuring it wouldn't play any role. Maybe I'll have me a little shooting war! I wonder if the AI knows not to glass an enemy homeworld that's also their homeworld, haha!
Question:.The pop and industry an NPR generated with is based.off of what you have when you meet them, right? I'm curious because I just conquered the first NPR I met and he had a bit more industry and pop on his homeworld than I had in my entire empire. Going strictly by the signatures, the smaller one's about the size of my original empire plus the NPR I just ate before meeting these guys, and the bigger one's about 50% larger. So, if I get into a war with these guys both at the same time, I'm looking at fighting about 2.5x my population and industrial capacity... Or effectively 5x because half my pop and IC is still subjugated
. Think my best bet is to hope they whittle themselves down?
