I've built a quick little script to rapidly build out star systems according to the ruleset in the Galaxies document.

Couple of things I noticed.

1) Not sure how to call a system importance on the first star generated. There are certainly chances that the extra stars built will be much more attractive than the first star generated.

2) Also seems hard to make sure that the planets that generate will be according to the system importance guide.

3) Jump lanes looks like they are determined based on the first star's characteristics. Because each star is randomly spun up, is that how it should be done? I suppose we could compound the jump lane modifiers from the Luminosity Class Table for each star? (Note, the python script isn't doing jump lanes yet.)


For example, here's a sample output run from the Python script.

Here's an example off the next run of the program. Got the six star system. Rolled like it was in a Firefly universe. (Which maybe is okay?) It rolled as Major, but with multiple stars, wow, 5 garden planets in one 6 star system.

(Note: Jumplanes aren't converted to VBAM-Galaxies yet.)

Bumping this, because it's germane to the other thread where we're talking about system generation. I am doing it in C# instead of Python, but the problem is the same.

As I understand the sequence.

Roll for number of stars in the system.
Roll for star in system, determine system importance.
Roll for planets in Inner, Middle, Outer zone.
Each planet gets it's own Type, size/cap, Raw, (& optional Bio)

When I do it like that, it's possible, even fairly common, to get two or more stars in a system with widely difference system importance rolls. If, a system is lucky and it rolls a couple of stars and they all rolls major on the importance checks, it gets to be a VERY desirable system. Feels a little too spikey for me.

Options as I see them:
* Make all stars only use the first system importance roll. This keeps it pretty much static for planets regardless of number of stars. (All star+ systems assumed to be close neighbors.)
* Make stars in the middle and outer zone even less desirable from a raw/bio prospective. Here is where bio could potentially shine for me. If I only give BIO to systems in the inner zone, and say you can only place a colony where there is bio.... that might take away the spike enough in terms of desirable worlds. Could still get a stacker, where far neighbors all roll Yellow star and get good inner planets.

Part of me likes the idea of a Bespin Cloud City. Maybe colonies cost more in middle and outer zone planets? That would also take away some their appeal unless they totally were RAW rich.
