Well, I just found out GalCiv2 has a massive error!

Apparently, green stars do not exist;

So, maybe not include them in GalCiv3?

Also, will we be seeing binary/trinary etc star systems?

Everyone knows that in real life the Drengin Empire destroyed all green stars because green is the color of weakness.  

How could Stardock possibly make the mistake of including green stars?

Well, that's just one scientist's view.  Here's another...

The answer is that there are stars that are green, that is, they emit their peak radiation at a wavelength that we define as green. In fact, the sun is a yellow-green star so is close to that temperature.

So there are green stars, including our own.  Our eyes just deceive us is all.

According to that post there is no purple stars either, Although no one has claimed that Galactic Civilizations is Non-Fiction and based on scientific facts so with that being said, the more color variation the better

Who cares if they don't really exist, after all, at one time we thought the planet was flat, that everything orbited around us and we were the center of the universe.  How very little we actually know about the universe, let the game be what it is

Actually, the article says that there are purple as well as green stars.  Just because we can't see them doesn't mean they don't exist.

Hahaha!  Yeah, that was pretty silly of us.  We all know that the center of the universe is Omicron-Persei-8.

I did not like green stars. For starters, unrealistic. Secondly, usually they had a bunch of dud planets that left me feeling icky!!!

Weren't green and purple stars introduced into GalCiv for the purpose of indicating that there was something special about.. or within, the solar system, perhaps that they had an extra high quality planet, or that there was something special about one of the planets orbiting the star? With my fabulous memory (I can even remember things that never happened ), I do remember them being added during the test cycle of either GC1 or GC2.

Ugh...here we go again....

Quoting MottiKhan,

First, let me pose a philosophical question: what is green?  I mean, it is a color, but how would we define green?  One could argue that green is simply a range of certain wavelengths for electro-magnetic radiation, but then that begs the question: how was that range of wavelengths determined?

Ultimately, green is simply green...it is an interpretation of our brain, a "figment of our imagination"...to say that a star is actually green but it doesn't appear green because our "eyes deceive us" makes absolutely no sense...green is defined by what our eyes and brains interpret to be green -- if it doesn't look green, then it isn't...

Now to green stars...stars are great examples of blackbody radiation -- the radiation they emit is related to their temperature...the higher the temperature, the more radiation you emit...however, you don't just emit more radiation -- you also emit radiation of higher energy (which in turn means shorter wavelength)...it's not a simple matter of "this object is this temperature so it emits this color"...rather, objects emit a spectrum of radiation...

For our star, the peak wavelength does fall in the "green region"...but stars don't emit light of just one wavelength, they emit an entire spectrum of radiation...while our star emits lots of green light, it also emits lots of yellow and red and blue....when you mix all the colors up, your eye sees white, and that is why our sun is classified as a white star...it is not technically green, that is complete BS -- if it was technically green then it would look green because green is defined by our eyes and brain...

The only way a star could be green is if there was a specific element with a specific electron decay that emitted tons of green light...in the "real world" that just doesn't happen, at least not to our knowledge...but since we are talking about a universe with mythical beings and ships that can destroy stars, I won't say it is impossible for a star to be green in the Gal Civ universe...but there better be an explanation for it (such and such the Mithrilar sprinkled pixie dust on it) because it ain't happening naturally...

In any case, our sun is most certainly not green....

With telescopes we are easily able to see an immense number of stars, none of which are green...even if there are green stars, it's apparent that they are so rare, statistically we would never expect to see them in a realistic random map generator that technically could spawn them...

I might as well say unicorns do not exist, at least not to our knowledge...you might actually have better odds finding a unicorn than finding a green star...

You are of course welcome to cling to a fantasy and argue that since we can't prove green stars don't exist anywhere in the universe (since such a claim would be unprovable), we might as well implement them in game...it is a game after all, right?  Anything should be possible, right?  And at that rate, might as well put unicorns in Civilization 6 since, well, it's only to our knowledge that they don't exist...

I could care less whether green stars are in the game or not...it's just a game and quite frankly how they look aesthetically is going to be a bigger factor to me than whether they are realistic...but don't kid yourself with false hope and misinformation -- if there are green stars in GalCiv3, it is because someone at SD decided they look cool, and not because science suggests there might be some...well, real science anyway...

Now there ya go ..... just shows the new technology bound up in Version III .... the good guys finally dumped that old early 21st Century technology so they could save save The Universe - and people start to get serious nostalgia pangs.

Sheeesh .... some scientists need to get with The Program...... and dump the Retro Look, its so ..... yesterday...

let me ask you a philosophical how do you know that the green your mind tells you is green is the same as the green my mind tells me is green

a little off topic im not asking about the color emitted by a star but the interpretation of that color by our minds

     Since when is 1 in 6 * 10 to the 21st power unrealistic. They say evolution is probable which is 2.4 times 10 millionth power that we evolved from the ground with the right conditions. Out of the estimated planets in the universe the estimated number of planets with earth conditions is 10. 

     According to recent astronomical discoveries going off the fact that all 8 of our planets orbits r considered round. They have found that only 1 in 1000 planets have round orbits. The rest r eliptical.

     Most stars r red even if our sun is yellow.

     Most stars come in pairs of 2-4 and not 1 even if our sun is by itself in the solar system.

     Just some notes on whats realistic.

see this post from harvard's website, http://www.cfa.harvard.edu/news/2006/pr200611.html, it states that in fact most star systems are single and most planetary systems are single, as it's believed that it's harder for planets to form in a multiple star system.

Although I'd like to see multiple star systems in the game, I wouldn't like it to be the common theme, and should stars be any color it would be acceptable.

Why not have brown dwarfs??

Here's a philosophical, no a rhetorical question for you. How far off round does a planet's orbit have to be to be considered elliptical. I just checked wikipedia and found:

A circular obit is one where the eccentricity (orbit deviation) is 0.

A Kepler orbit is one where the eccentricity is between 0 and 1. (non-inclusive). This term comes from Johannes Kepler of the early 1600s.

Parabolic escape orbits and hyperbolic orbits, from what I was able to understand, seem to be one shot occurrences, since Wikipedia describes them as cases where the orbiting object escapes the orbited object. I really don't understand why these are called "orbits", but I don't think they are germane to our current discussion.

The use of "round" in reference to a planet's orbit is not used, but "circular" surely fits what you are describing.

However:

Mercury has a Kepler orbit, with an eccentricity of 0.205

Venus has a Kepler orbit, with an eccentricity of 0.0067

Earth has a Kepler orbit, with an eccentricity of 0.0167

Mars has a Kepler orbit, with an eccentricity of 0.093

Jupiter has a Kepler orbit, with an eccentricity of 0.0488

Saturn has a Kepler orbit, with an eccentricity of 0.0557

Uranus has a Kepler orbit, with an eccentricity of 0.044

Neptune has a Kepler orbit, with an eccentricity of 0.0112

And, just for comparison,

Haley's Comet has a Kepler orbit, with an eccentricity of 0.967

As you can see, all eight of Sol's planets except Mercury have a small orbital deviation, all less than 0.1, but none of them are considered circular.

     I'm actually going to reply to both of you. According to the astronomy teacher I had this year Who is currently working on the probe that is studying weather patterns on Jupiter who is currently an astronomer says that astronomers consider that deviation circular, and they only find 1 in a 1000 planets circular. If they r referring to an orbit eliptical they mean a lot greater eccentricity. I don't make the terms they do. The reason I mentioned what my teacher does for a living in 2013 is to point out his qualifications. In spite of termonology U r right not a lot of objects in our solar system is perfectly circular.

     Now thanks for the information on single stars I guess I was wrong about that unless they have changed their opinion about that since 2006. As far as the planets go a lot of things have changed like they have found at least 10000 planets because of the planet finding probes. The orbits of every planet they have found is more like pluto than Mercury, and the smallest sized planets r now the size of Mercury.

     The orbits of the planets r not perfect circles, but they r circles as far as astronomers r concerned. I guess they compare the orbits to other objects orbits, but out of 10000 planets only 10 of them don't have orbits that r more like pluto's. 8 of those r in our solar system. I guess that modern Astronomy, Wikipedia, and Johannus Kepler disagree on this issue. I would like to point out that Johannis Kepler couldn't really see our stars that well. Astronomers and probes can at least see it better for right now. Later they will probably see it better.

     About the sneeches kind of funny haha.

According to Wired, that's 10 billion Earthlike planets may exist in the Milky Way. I mean, I have no issues with bringing up science, but how does one even predict there are only 10 Earth-like planets in an infinite space? That makes no sense.

According to my astronomy teacher given the conditions that make a earthlike planet. Mainly things like our moon and things like saturn and Jupiter. Our near circular orbits. Thats just a few out of fifteen conditions that make our planet the way it is. It really the difference based on modern knowledge of astronomy and wishful thinking. Oh I can find the conditions, but I'm not smart enough to crunch the numbers. Most of these numbers come from evolutionists and astrobiologists, but mainly evolutionists trying to put in biased conditions to create a scenario for life to exists in a computer simulator, and that is what a computer pops out. This also includes our knowledge of physics, microbiology, and chemistry. It's the difference between science and wishful thinking. Some people r trying hard to make science not to admit to a creator, but computers r there biggest enemy. They aren't smart enough to be biased.

Yes, the Drengin Empire fleet orbiting Earth (which inside a giant bubble of invincibility) demands realism.
