Ha!
I spent like a week thinking how to name my future nation/government body I'd be playing, at least the one I'd be doing my next AAR about. I studied material/refreshed my memory about a lot of sci-fi and existing structures/governments, ranging from UN led armed forces to the books I read years ago.
And then it struck me. Days later, I came up with calling it... *spoiler alert*
Humanity
ps: Oh... Firefly reference. How could I...? Shame on me!
