Today I came across a neat example of automated star-system generation, based on the design sequence I wrote for GURPS Space, Fourth Edition back in the day.

It looks like a robust code base, supporting a web-based interface. You can generate star systems at random, possibly forcing a few parameters (existence of a garden world, position in an open cluster, and so on). You can pick from several naming schemes for the resulting planets.

The output includes a neat animated map of the system, and hierarchically tabulated information for randomly generated stars, planets, and moons. All in all, it looks very slick, and it seems to reflect the original game rules pretty accurately.

The source code for the project can be found at Jan Sandberg’s GitHub repository. The redditor Myrion_Phoenix hosts an instance of the application on his website as well.

I’ve mentioned my own more recent work on Architect of Worlds – it would be neat to see a similar automated version of that once it’s ready for release. In any case, this application looks very useful for folks who are running hard-SF games, whether using GURPS Space or something similar.
