Nice to know someone likes my campaign! I'm glad it's been helpful to you.
I've enjoyed Aurora's automated NPR's, as they can be unpredictable and, as a player, you generally don't know their strength, so they can be interesting to play against. As a main antagonist, though, they leave a lot to be desired as it can be hard to fit their actions into a narrative. In several of my Aurora campaign's I've played all of the races, either with NPR's turned off or just used as a distraction.
Back to work on Cold War!
