Glaring Error in d20 Future...

[Psion]

If you are serious, go bring this up with Malenfant on the COTI boards. He's frequently ranted about poor world generation systems and his web site has a whole bunch of really good information.

You mean like this thread?

They don't look green. F-classed stars are yellow-white visually. If a GM ever said the words "Green Star" I'd leave the table.

Fortunately, I'm the GM. So even though we have magic and cyborgs and rampaging million-year old androids in Exodus, we don't have green stars.

So... If the visible spectrum on a star was green in game... you'd leave?

What if it was a plot device? Something wrong with the star, and the inhabitants of the star system needed help?

Well, it's impossible to write "realistic" star system generation because we simply don't have enough data on planetary systems and how they form to say what is realistic.

Most of the extra solar planets that have been detected are Jupiter sized or larger (which is generally why they have been detected).

THere's a pretty decent site

http://www.extrasolar.net/mainframes.html

Which has comparitive models.

A lot of the planetary systems we've found consisted of a very large planet (bigger than Saturn, smaller than Jupiter) very close to the sun, then a largish planet out around where we have Jupiter (usually larger than Jupiter, though).

There are some with a Jupiter sized planet around where Jupiter is and not one near the planet, and so might be like our solar system, but we really have no idea what else is in the system. It's just a guess.

Though d20 Future pretty much dodges this by not having a planetary generation system. (It does have one for the number of planets around stars, but not one for planets, as near as I can tell...)

i like the system generation system (that sounds weird :\ ) in GURPS Traveller: First In. however, it is a bit, ahem, involved (figuring out the planet's black body temperature and albedo before figuring its actual average temperature, and so on). but if you like detailed, it's quite a nifty system.

i also like the freeware program Stargen (http://www.geocities.com/TimesSquare/2691/stargen.html) -- it may not always give 100% realistic results, but it can generate a huge sector filled with hundreds of star systems at the push of a button.

Sheesh.... I'd rather run it off the cuff, and keep notes.

Two of my favorite resources.

I am actually trying to work out some better generation algorithms for Stargen with the writer.

Boy, you must be a barrel of laughs to play with...

I love when science kicks down the door of your rational mind and holds the joint up.

MY future game will have green stars.

Just so somebody can get all huffed up about there being no such thing.

And I can haul that article out, then we'll ask the android what HE sees.

Really I don't 'see' what the problem is. Green stars do, in fact, exsist but only if viewed by something other than the naked (human) eye. Ship sensors and such would class the star as 'green' but everyone would see it as a white/yellow star since the human eye can't make the distictions. The android would mutter something about 'blind organic meatbags' and everything is good!

oh hey! that's cool. i never noticed your name in the credits before, but there you are.

good luck with that. i definitely appreciate the work that's been done on the program, and have gotten a lot of use out of it.

That's funny, I thought the reason that the sun looks yellowish even though its spectrum peaks in the green, is that the sky is blue. I.e. some of the blue gets scattered out of the sun's direct light and spread around the whole sky, leaving the sun looking a bit wan.

It should be easy enough to figure out which answer is right. If I'm right, the sun should look greenish from space.

Any astronauts on ENWorld, please reply. (Remember, helmet visors and shuttle windows have some funny protective coatings, so you have to do a bare-eyes test.)
