Hm. I tend to have the most fun RPing odd species with unique biology and sociological traits, so yeah, an organization isn't a good match. As a break from playing big empires though I might go with a species that has very little in the way of any sort of central leadership and is more just scattered independent tribes. I'm thinking... maybe a human-bug hybrid species with some limited shapeshifting abilities? With most of them living on ships as explorers/pirates/merchants? Thoughts?
