Research/Trade Treatys

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

Now on to your primary question. There are two types of treaties: Research and Economic. Every civ gets one of each. If you choose to gift/trade/sell a treaty to another civ, they will receive 10% of your research/economic output. This costs you nothing. It is 'found money', as it were.

These treaties do indeed strengthen relations. Only allied civs have closer ties.

Yes but why BLUE? Why do our eyes see a specific refraction of color as that particular shade? And why do we call that shade BLUE?

Seriously, thanks for the definition. I kind of figured that it would be something like that. Is there any down side to picking one civilization over another? If that Civ happens to zero out their econ/research, does/could it have negative impact on mine? Does this get broken when I finally surprise attack them?

Yes it does. As an added bonus, you'll get a permanent relations hit as someone who back stabs friends. I think it's with all races. So stab those whom you have treaties with...last.

The hit to relations comes from attacking civ's with whom you have GIVEN treaties, not ones you have them FROM. If you have a treaty from a minor race, feel free to atack them.

You can not be penalized if the rac thtat gave you a treaty has a negative economy. (I don't think). I've never seen this though.

I try not to give either of my treaties away since I'm just helping out a future enemy. But I will still do it for the right price. Like a planet or 2.

You can see what you are getting from the treaties. On the economy screen it will be listed along with you tax income etc.. What you get from researcg treaties can be seen on the screen with the actual tech tree.

The treaties are good for relations mostly but can be some what lucrative if you get them from everyone, especially all of the minor races since they are easier to get.

I use my treaties to butter up my neighbours. The two races I feel are most likely to declare on me get the treaties, while I can then focus more on research (with a weak military), out-tech them, and by the time they've got angry enough at me to declare war, I'm able to crush them.

You can also use them to booster a weaker race to make them a bit tougher, and of course if you receive them they provide a valuable boost to your own economy/research.

Thanks everyone for the feedback. Much appreciated. I now feel fully armed to eXploit research/economic treaties with my "Allies".

Have you seriously ever negotiated for a planet? More than one? I have never successfully done this. Either I don't have enough BC or they want the world of tech just to give it too me. I usually figure that it is just as easy to take it from them.

But I also want to play a trade/manipulating game one of these times. You know, where the end result is that everyone bows down before me and gives me lots of stuff for free and without me ever firing a shot.

I have, it was two planets owned by the Arceans. I gave them my economy treaty and a really high end tech like Aeron Missle defence (i'm using lasers).

It was important because it was with a group of planets way in the corner that were being shared by 4 civs. The purchace took the Arceans out of the area and then i took the Korx's planets in our war. So now i can overwhelm the Drengin in this corner when the time comes.

I don't know what the AI uses to value planets though. Sometimes i can mock-offer like 10 of mine and still get a "No" when i want them traded for just one AI planet. In the game i mntioned above, I can't get the Drengin to budge for anything and they have many planets. So i don't think it has to do with how many planets they have left.

Actually the basis is the physiology of the eye. Our retina contains three different types of light receptors for vision at daytime (cone cells) that each have distinct sensitivity for a definite range of wavelengths. It is a distribution of probabilities if a rexceptor gets activated by a photon with a distinct wavelength, each type having its own most likely set of wavelengths to be activated from. The cone cells have 3 subtypes, with the S-type being activated in blue wavelengths, the M-type in green and the L-Type in red wavelengths. This is represented in the RGB-color scheme which you may find in context with monitors and other visual technology. The perception created by your brain is not which receptors get activated, but what the relation of the activation of the receptors to the others is. Your brain calculates the relative activation of each receptor type in relation to the others and translates it seamlessly into a perception of color. This is the physiological basis of the RGB-system, which uses red, green and blue light in different ratios to create the sensation of colors.
