Die Drop Planet Generator for Sci-fi Games

I am currently working on a book for the awesome White Star system that I’ll be using to aid in my Strange Stars game.   I love die drop charts so I figured I’d create one for this.


Simply roll a d4, d6, d8, d10, d10 (%), d12, and a d20.  Then roll a d20 and consult the name chart.  Boom.  Done.  I have also provided two examples that are “flushed out” after I consulted the results.

Planet Two


d4- Tech Level

  1. Low
  2. Medium
  3. High
  4. Futuristic


d6- Population

  1. Abandoned– The society is gone- abandoned for whatever reason. There may be a few survivors here and there.
  2. Sparse– There are a few colonies throughout the planet. Most likely small outposts.  Probably no more than several tens of thousands inhabitants on the planet.
  3. Decent– A few colonies throughout the world, or a few cities, or one large city. Roughly a population of several million inhabitants.
  4. Busy– The planet is teeming with inhabitants. There are several large cities on the planet.   The planet has roughly a population of several hundred million to billions.
  5. Packed– The planet is bustling with inhabitants. There are several massive cities on the planet.  The population has roughly a population of several billion people.
  6. Metropolis– The planet is over-populated and may even be one giant city (GM’s call). The planet has a population of tens of billions of people.

Planet One

Example One: Carcass is a failed colony world that was abandoned after the tensions that ran high between two rival factions exploded into a small but fierce civil war. Many argue that the colony didn’t survive due to the low tech that was provided for settlement.  Carcass is an ocean world where all the structures are built upon floating barges.  The architecture of all the buildings resembles large round glass buildings.  Earthquakes are shaking the ocean floor and causing massive waves to rattle the area, destroying many buildings and damaging the abandoned shuttleports.


Example Two: D-5517 is planet covered in massive mushrooms that stand 20’-40’ in height, and is renowned for its advanced technology and its highly dense population of tens of billions of inhabitants.  The capital building of D-5517 is a spaceship that hovers in the sky.  Most of the buildings are constructed of a bronze metal that is warm to the touch.  Recently D-5517 has had its share of troubles: a strange breed of fuzzy rat is breeding at an alarming rate.  In a few days the cities will be overrun with these cute, but annoying, rodents.  Also an unrecognized configuration of starship has crash landed in the capital city.
