They don't. I believe only two campaigns, including Dawn of Sol, have done so. And Blue Planet's 'utopia' was significantly more complicated, since it was neither utopian nor universal, merely a sort of fledgling stab at it.
Most campaigns take the Inferno route: Inferno, BWO, Machina Terra, Olympus Burning, so on.
I've also got to dispute that this campaign was 'great'. Very promising, perhaps, but I think it needs to be taken back for a long round of polish. It's not up to snuff.
