"Civilisation Power" Question

from GalCiv3 Forums

So having played about 20 hours of GalCiv so far and gotten into a few Gigantic maps full of Gifted AI and it's been an experience. I am by no means good at strategy, though I do enjoy playing them.

With that, I have a question.

How does the AI determine power with which it bases all it's major decisions on whether to attack off of? I have had a hostile alien empire with very little other than a massive amount of mining starbases decide I was for the chopping block and declare war despite the fact I had more of a military at the time and it only had a few ships with very basic weapons tech.

Is the calculator taking things like colonies, starbases OTHER than military and ships without weapons into account when deciding if it's civilisation is stronger than your own?

I'm using the 1.03 beta patch, just for reference.

It uses Vodoo. :D

Seriously though...

 

I have been wondering this as well since I've had an empire that is about twice as big as any of my neighbours and a fleet that has chewed through everything it's gone toe-to-toe with and I still get threatened with demands for tech and tribute.

Also when I mouse over other empires in the Diplomacy screen I am "Weak" and "Ripe for Conquest" oftain at the same time as I am taking worlds off others and wipeing out fleets of enemies and pirates.  :rolleyes:

You can spike your 'Power' rating by also going one turn at 100% Wealth creation.  Does little for you as soon as you change your Econ but it does show that the formula overrates the Wealth component of an Empire over that of Production and Research strength.  (If you 100% Manu or Sci your Power doesn't spike.)

Yea this power rating defiantly needs work.

Based upon some variables in GalCiv3GlobalDefs.XML, I would expect that a civilization's power rating is calculated as

[power] = 0.3 * [total production points] + 0.002 * [battle rating] + 0.001 * [treasury] + 0.1 * [total influence] + 0.25 * [number of techs researched] + 0.1 * [number of ideology traits]

The constants are from the v1.02 GalCiv3GlobalDefs; they may differ somewhat in v1.03. I haven't looked at v1.03, so I couldn't tell you. I don't know how the game computes 'battle rating,' but I'd be a bit surprised if it weren't something like the sum of the fortitude and threat values of all the ships you have, or a sum of the attack, defense, and HP of all the ships you have, though the values may be weighted to some degree.
