What do you think is the more interesting kind of worldbuilding for space opera:
Warhammer 40,000 and Star Trek, where Earth is humanity’s capital and sacred homeland
Dune and Legend of the Galactic Heroes, where people know humans are from Earth, but it doesn’t get any special privileges in the galaxy from that, not any more than Africa does on modern Earth
Foundation and The Culture, where Earth is just another planet and nobody thinks it’s special at all
Firefly and Titan A.E., where Earth was dramatically lost
Or Star Wars and L-Gaim, where humanity’s homeworld is forgotten and irrelevant?
