Rogue Planet and other Universes
Rogue Planet should stand on its own and is not actually set in any other fictional universe: however it can be placed in a wide variety of other settings. A bit like the D&D adventure modules of old could be placed in different fantasy campaign settings, so too Rogue Planet could fit in to an existing RPG campaign in a better-known universe. These possibilities include (but are certainly not limited to): Star Trek Star Wars Doctor Who Battlestar Galactica Warhammer 40,000 Firefly Traveller Star Frontiers If you make Rogue Planet part of a larger setting you could well either have characters, factions or alien races from the well-known franchise turning up on Rogue Planet. Wookies, Daleks, Romulans, Eldar or Xenomorphs could all find their way and cause their unique brands of trouble. Of course, for some of these some tweaking will be necessary. For example adapting this to Star Wars would mean colonists coming from another homeworld other than Earth (perhaps Corellia or Coruscant)
