Again awesome mod. Yeah I have been playing around with your mod. So this is very familiar, thanks for calling out the exact location and confirming what I figured.
I'll probably throw a few other things your way as well. Let me know if you would prefer I not.
One thing I noticed on my first play through. (No changes to current build). Lost as the Borg. Random cluster galaxy, I had my own cluster to start out with and a few independent colonies to take over. So quickly had 10 colonies going. I could not keep up with almost everyone else's tech rate. I had numerous tech bases, three scientists. I showed I had 700K or something max and I had so much extra research facility, it wasn't funny. I fast tracked so much I had little money for anything else. Yet all but one wonder was built by another race.
Also, I left colonization on auto, I found the game was queuing up colony ships from the closest planets to what could be colonized. This caused all kinds of planets to be colonized by enslaved races, which caused all kinds of issues. And back to the lack of migration, No growth and no "borg" showing up to live on them. A few did see migration, but only a few.
I'll try the do not accept, but isn't enslave a more forceful version of that? I had all others as enslave. This was because I didn't feel extermination with the overall DW game mechanics was what borg should do, but I'm going to try, migration change and set extermination. Since this suppose to be, assimilation, I'll see if I can't figure out how to ensure that extermination provides a 10% growth bonus. Maybe make that even higher.
My thoughts is the Borg should require almost every other race to come together to really push or take them out, but I also understand this is a mod, and creating a race that causes almost everyone to not want them to appear in their game, because it just turns into: Must take out borg, ASAP.
Also, as a Star Trek fan, only from NG forward. The borg ships were Huge. Why is federation +30% ship size if borg is only +40%. You don't really need to answer/defend this. Just figured I would not see bigger military ships than +20% if borg were +40%.
I think I'm rambling....
Last quick thoughts, I know you didn't ask.
Yes, federation have bigger ships than other races. But, federation ships are civilian and military mix, with huge space taken for families on board. So to me the fix would be. Federation ship size should be standard, but have the ships image scale to larger. It looks like you can't tweak the builds to have excess hab modules, but that could be an alternative. But then any "ship builder" is likely to remove them.
A Klingon bird of prey is half the size of it's equivalent fire power federation ship. And I believe the Romulun etc are the same way. The one huge Romulun ship in TV/Movies severely outclassed the same federation ship.
Ok, going to go tweak out some things, like the migration factor.
Thanks for all the help and the great mod.
