SSO has a number of semi-hidden references throughout its artwork and flavour text. The whole feel is entrenched in film futurism from the '70s and '80s and retro futurism from the '90s onward, almost any film or TV show you care to think of is referenced. However there are several very specific references. I won't say the exact references since the fun is to find them but will state the source in each section (this does not contain spoilers, but those who wish to spot the references entirely unaided should stop reading now):
Locations - Alien, Silent Running, 2001: A Space Odyssey (twice), Star Trek.
Movement: Cowboy Bebop, the works of Philip K. Dick, Judge Dredd, Rogue Trooper, Star Trek.
Crew Cards: Apollo 13, Silent Running.
Main Rules: Star Trek.
Some are fairly easy to spot but some are extremely obscure. Happy Spotting.
