I think I've managed three.

Re: [Space] System Generator
 

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

Re: [Space] System Generator
 

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.

Re: [Space] System Generator
 

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.

Re: [Space] System Generator
 

The 4e system generator is kinda dated now, though, isn't it? Given what we now know about exoplanets? I'd be more interested in an updated version.

Re: [Space] System Generator
 

I don't think that info has really settled down. It just broke what we had before. If you can find a source that really talks about that sort of stuff, I'd be more than happy to look into it.

I've got a java program from college days that's close to a workable state --- or it would be if java as a brand name hadn't keeled over and died. The big thing that made it different was it had a gui interface that let you move planet positions once generated and tweak numbers on the fly. It also kept track of several systems.

I probably ought to try and dust that thing off sometime. Maybe get it to a better language. Though I'll be the first to say it was poorly written by a first or second year programmer.

I'd be tempted to move to javascript, but I think there are legal issues with that (primarily that you can read the tables and that's a substantial rules reprint).

Jon F. Zeigler is working on a new version for independent publication; see https://sharrukinspalace.com/ .

Re: [Space] System Generator
 

That seems to be languishing on his backburner though.

I'd love to integrate such updated data into the GSSG, but for now we stick with what's in the book for maximum compatibility.

Re: [Space] System Generator
 

It's a great program. If I were to add some functions to the wishlist, I would ask that:

1. The planets would be in a random position in their orbits when we first see the system.
   
2. That the system map could be advanced by an amount of time the GM chooses.
   
3. Distances between planets at any given time could be calculated.
   
4. Orbital positions could be tracked while the characters are away in another system.
