Any tech tree mods out there?

This is the only mod I have seen that changes Tech Values, BUT, I do not think it has been updated for 1.7.

The other alternative is making a copy of GalCiv3GlobalDefs.xml from the installation directory and placing it in My Documents/GalCiv3/Example Mod/Game and editing the lines related to tech increases:-

    <!--Each time you research a tech in any tree the cost of all techs are raised by this exponent-->
        <TechInflationExponent_All>1.25</TechInflationExponent_All>   (25%)
    <!--Each time you research a tech in any tree all techs cost is increesed by this multipyer.-->
        <TechInflationMultiplier_All>0.1</TechInflationMultiplier_All>     (10%)
    
    <!--These values allow us to further inflate techs on a per tree basis, this is to discourage the
    player from drilling down a single branch of the tree to quickly, and over specializing.
    I have removed the exponent, and have only a small multiplier, since it is added to the overall inflation settings.-->
        <TechInflationExponent_Tree>1.0</TechInflationExponent_Tree>     (0%)
        <TechInflationMultiplier_Tree>0.1</TechInflationMultiplier_Tree>      (10%)
 

Increase the values in red, I would do it in small incremants myself untill you get the balance you want. Otherwise its a case of editing every TechTree from every faction to increase the Cost values, alot of work.

A lot of work indeed. There are 3349 <ResearchCost> entries in 10 tech trees.

Now if some kind soul would code a tech cost increase tool, changing the values would be quick.

You could even have different multipliers for different tech ages.

thats what I was afraid of

as horemvore said I may have to just play with the multipliers to find a good balance 

I'm not a Modder and some xml's can be quite complex, but looking at what you want to do, it wouldn't be too complicated to code a basic tool.

If you want I'll have a go over the weekend.

'Copy existing tech trees into a mod folder and modify tech costs with your choice of multiplier'

Is this all I need to do?

That's pretty much what I'm after

Ok, leave it with me. I have no projects on the go ATM.

I'll PM you when I have something

Don't rush to much I'm probably going to build a new map this weekend and see if a new patch comes up before I get to try it out

Sent you a PM with a download link.

Hopefully self explanatory how to use.

Should be version independent, unless the tech trees change drastically 

Thnx now I need to finish my map and start a new game

Updated the Mod tool as requested.

Prompts to overwrite existing mod folder and remembers last location.
