Yes, thanks for the informative reply. Of course I found this out myself not a few minutes after posting, and said to myself, "Self, how could you not see that file?" But the thanks is still sincere nonetheless.

Edit: What I've done is set the tech requirement for Planetary Bombardment in InvTactics.XML to Technological Victory. This effectively removes it from the game without deleting it, as I didn't know if that might cause problems.

double all logistics bonuses -> woot

Back to the original question... has anyone added a tech? is it hard? what do you have to do ?

I've been wanting to make a couple of my own but not sure if I need to do anything special to "attach" it to the tree.

I figure I can do most of the xml stuff just fine, borrowing the tags from an example.

ok thanks. can't wait to test it out then.

There is no scripted list, and the AI adapts to tech changes by itself. (So if you were to up the bonus given by basic logistics, the computer would put a higher priority on researching it.) I would assume that it would adapt to new techs by itself as well.

Cool - I've been looking at modding the tech tree - (as in a 'total conversion' for a while - I was looking through the xml file earlier and was wondering how well the AI would cope with a completely different tech tree - I guess I'll have to try it and see though..

(I wanted to do a total conversion with teh first GC, but even using the Editor for that it didn't seem to let me play around with the existing tech tree - only add new stuff to it :-/ ).

P.s. What exactly do the Model entries refer to in teh techtree.xml file?

(Now I'll have to go and look through all the other xml files and start planning everything out).

Oh - 1 more thing - is it possible for a tech to have more than one tech requirement for it? (Similar to the first game) - since, of course, in this one - each tech only has one needed before it...

I'm a long way from doing this (still trying to figure out prerequisite stuff) but one goal I have is to add a tech that gives a new module to the tech tree, one that you could put on ship that would work kinda like a constructor (a one-use ship in other words) that instead of upgrading a starbase, would upgrade a planet's score by 1 (making a 0 colonizeable, 1's into 2's, 2's into 3's, etc.) as well as increase the useable number of tiles. Any ideas how to go about this, what things I should look at, or general advice on how to proceed?

I am trying to add a tech to the tree branch and every time I add a tech by its self or add a tech under anything or after anything, it is all ready researched, is there anything that I can do to fix this? I would like to add a seperate tech tree branch in this game.
