Space Viking Small Planetary Cluster

Here is the small planetary cluster I generated using my revised Space Viking planetary world generation checklist I posted.  I welcome comments.

Harpe is the stand in for a Sword World.  I did not roll for its UWP.  I created it to suite my needs.  For the rest I used the generator.

I created the map using Alex Schroeder's subsector generator and map creator.  It includes a Classic Traveller map generator.  It's pretty cool.  It will create random subsectors or you can input data you generated.  It will also show multi-planet governments.

Space Viking Subsector Generation Thoughts 2

 After several false starts, bouts of gamer ADD and some revisions, I took a look at the thoughts and ideas I posted here three(!) years ago and simplified them.  I wanted to keep the generation rules as close to the original checklist as I could.

Keeping the tech level of most worlds low was one one of my concerns.  Controlling the starport type was a simple solution and also fits in with the fact that most of the settings worlds either don't have starports or only have primitive ones. 

I did discover when I was playing around that populations seemed too small so I changed the population roll to a straight 2D instead of 2D-2. I still cap it at A though.

I'll create a small cluster of worlds and post it soon. 

Piper World Generation rev. 1
  • Determine world occurrence (1D for 4, 5, 6 is standard). 
  • Check system contents table for details of world. 
    • Find Starport type.  Used modified table below. 
    • Check for Viking (scout) base.
    • Check for gas giant. 
  • Name world. 
  • Generate universal planetary profile for the world. 
    • Planetary size: 2D-2. 
    • Planetary atmosphere: 2D-7 +size. Tainted designation indicates pollution in the atmosphere, however no filter mask required.  If planetary size is 0, the atmosphere must be 0. 
    • Planetary hydrographics: 2D-7 +size. If planetary size is 0, then hydrographics must be 0; if atmosphere is 0, 1, or A+, then apply a DM of -4. 
    • Population: 2D. No population if atmosphere 0-3, A+. Cap A.
    • Government: Roll d6, 1-3 Balkanized. When the planet is detailed, roll D3+1 for # of major political units.  Governments can be rolled for or determined by GM. If not balkanized 2D-7+population.
    • Law level : 2D-7+government. 
    • Technological Level : 1D+DMs from tech level table. Hard cap TL 10.
  • Check for naval base as appropriate. 
  • Note trade classifications based on universal planetary profile. 
  • Note statistics for reference.
