That's excellent. I'm going to do one run-through with the following:
Fanatic Materialist Xenophile ruled by a Science Directorate
(tentatively named the Kurzweilians)
Intelligent
Sedentary
Natural Engineers
Summary
Scientists are eligible for Leadership
+35% Engineering output
+50% Migration time
+20% Physics output
+1 Research alternative
+20% Society output
-10% Xenophobia
They have an almost religious devotion to the idea of creating a race of super-intelligent robots who will carry on their work, even if the robots kill them and everyone else in the galaxy in the process. They're xenophile in the sense that they don't feel it's their job to judge the worthiness of other species. They'll leave that to the robots. They also don't have any particular preference for war, peace, diplomacy or trade, and will do whatever they feel is necessary to further their research.
The problem is that I kind of feel like they'd use wormhole technology, but I think it would be more sensible to use warp or hyperdrive on my first run-through. Might just leave them until I have a bit of experience with the game.
