My campaign post is for the Spiritualist , Xenophobe , and Militarist ethics . Reasoning is as followsSpiritualist is incredibly useful for minimizing ethics divergence , and all three Theocratic government types are fairly strong in situational uses . Namely , Theocratic Republic is useful for happiness , the oligarchy is good for keeping rulers with good traits around for as long as possible , and Divine Mandate is literally Pops will not diverge from our government ' s personality cult under any reasonable circumstances . Xenophobe , despite making the rest of the galaxy dislike us , is useful for allowing actions that would normally be disabled for Republican governments , and also allows those things without wasting an ethics slot on Collectivist . Slavery and PurgingI do not recommend Fanatic Xenophobe because that makes being diplomatic with other Species practically impossible . Militarist is about keeping our pops happy and productive when we ' re at war . It also allows use of full orbital bombardment , and the Militaristic governments are useful for waging war and defending ourselves if we end up next to something dangerous like a hostile advanced start .
