Caprica is giving us, with it’s first two episodes, some excellent worldbuilding.  And I don’t just mean the excellent CGI of the cityscape — which I love.  In the first two minutes of the first episode (not including the pilot), they established a bunch of background elements that flesh out the world.  Blimps over sports stadiums (and beautiful designs for airships, at that), there’s a hint that cubits have “cents” — I deleted the episode off my DVR, so I didn’t get a chance to catch the word.

Later, we see that group marriage is legal but rare in the colonies (or at least, Caprica.)

UPDATE:  Cubits have “pieces.”
