Star System & Planet Maker - Ennead Games

This week PDF hilight is one that got a bit of notice when mentioned being used by a twitch streamer (Big ty to @16BitEric for doing so) and made me realise that “heck, people DO enjoy using my stuff” which as I was going through a big spat of self doubt and imposter sydrome at the time helped a LOT.

At the time of publishing, this has a Gold rating on DrivethruRPG, which put it in one of the top 3570 products (3.56%)! Not only that, but, until March 14th 2021, is on sale!


Star System and Planet Maker

“Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space…”
Douglas Adams, The Hitchhiker’s Guide to the Galaxy

You are out there, being busy and exploring the big an empty void known as space and you encounter a star. What type of star is it? How many planets, if there are any, are in orbit? What about the planets themselves? All these questions and more can be answered with this publication.

  • The nature of the star(s) in the system

  • Axil Tilt
  • Day/Rotation
  • Density/Gravity
  • Hydrosphere
  • Magnetic Field
  • Population/Lifeforms

Due to how complex the nature of star systems and planets can be in real life, this publication is not claiming in any way to be scientifically 100% accurate…at all. This is a deliberate design choice, to make it easier to use and not bogged down with too much detail. At the end of the day, this publication is for fun and idea prompting and assistance. If you need 100% accuracy, there are plenty of free books, websites and resources out there worthy of your time and attention.
