Mine is an Egalitarian, Xenophile, Materialist Technocracy. My guys learned long ago, that it’s best to plan ahead and live in harmony with nature and each other. They will terraform all their planets into Gaia worlds, welcome all who wish to be a part of their empire and grant equal rights and utopian abundance (Shared Burdens require Fanatic Egalitarian, too bad). I’m also thinking about vassalizing every other empire on beneficial terms, thus also making them part of my federation.
I once played a fanatic theocracy of bird people bent on converting everybody else to their religion. There can be no peace until everybody knows that the bird is the word.
