[Space] System Generator

Or you can just hit the random button and it does the whole thing for you....

I'm bumping a really old thread. I may have missed it in the discussion (I found some dead links), but did this program ever get made and if so where is it?

This was the link I had, and it is doesn't work for me now either: ultima.vsos.ethz.ch:8080

I believe this generator moved here.

Indeed, Mook is right. The Starsystem Generator is now at https://ultima.vsos.ethz.ch/starsystem-gen/

and it is indeed simply a hosted version of the code at
https://github.com/tschoppi/starsystem-gen/

[EDIT] This is not my thread! This is a much older one, that I didn't know about. So no, this isn't the originally discussed program.
But it does create systems according to GURPS Space 4e, and has both a web-based GUI and a CLI capable of generating LaTeX output, which can be turned into PDFs.

Yeah it is, great way to have multiple planets for the setting and avoid FTL

[Myrion]

Well, with the "Force Garden World" option, you get at least one habitable zone planet, and then you can just regenerate until you get a second one :)

Should happen often enough that you won't need hours for it.

With Seed 206366015 and "Force Garden World" you get one warm garden world (average temp 37°C, is the garden world) and one hot world (57°C).
The hot world officially has no atmosphere or hydrographic coverage, but you could just tweak it by saying it was terraformed.

There's another two worlds with significant hydro graphic coverage, but one is frozen and the other...
1648.4 K / 1375.25°C average surface temp. How is there still liquid water, you ask?

5671.52 atm pressure.

I don't know whether it's the same implementation as discussed originally in this thread, but the only starsystem generation project I know of can be found here: https://github.com/tschoppi/starsystem-gen

I'm actually working on one right now. Currently it just generates all of the stars in the system and their stellar characteristics up through minimum and maximum separation. I'm coding it in Python and it's currently a little over 800 lines long. I haven't worked on it in a while, though. I'm currently working on an article I'm hoping to submit to Pyramid soon.

EDIT:
Here's a sample output of my program so far.
