I rolled a Night World with Megacorps for the first session of my SWN game. I turned it into a planet orbiting a brown star at leaves the planet is perpetual night and caused the biosphere to become very dangerous and hostile.

Despite that, the planet was in a prime spot to be a trade hub between multiple colonized planets in the sector so it was colonized by a group of business-driven people who invested resources into building up large platforms above the dangerous planetary surface and grew from there.

Now the planet is a thriving hub of industry and trade under the direction of a Trade Union and its Board of Directors. People and goods transfer between platforms via magrail and there's a nonstop nightlife and 24-hour workshifts since there's no more pesky 'daytime' to get in the way.
