I've always wondered about this question: when a person's born, how would you determine if a person's a Libertonian, Corsair, Gallic, etc.?
Sure, you could say their physical features play out. After all, there were only 6 sleeper ships in the game, and they had distinctive features:
Liberty = American
Bretonia = British
Rheinland = Western European/German
Kusari = Asian
Hispania = Latin/Mediterranean
Gallia = French
But is that really all that we're based on?
Take for example, the Mollys. They're technically Bretonian, but they are considered entirely-different in regards to that they're Irish than pure British.
Or how about those that have been born on the far-fringes of the Edge-worlds, aka the Zoners, aka "melting-pot-faction-of-Sirius?" Isn't >600 years quite a long enough time for interbreeding with all 5 vanilla sleeper ship-races (not including Gallia, for obvious reasons) to make some physical evolution of some sort? America's only 300-400 years old, and they're already notably distinct from Britain, their motherland, in a sort of way.
I'm no anthropologist or geneticist (well... maybe I might become the latter in the future), but I'm just curious about how you would categorize a person's race if, for example, one parent's a zoner, the other parent's a Libertonian, and the baby's born in Planet Malta, but somehow the baby has Kusarian facial features?
