I am playing 3 earth-based empires this campaign.. They are all friendly with each other, and have a survey sharing agreement.
However, there's no alliance, and also no technology trading agreement.
But.. WHen One of my races discovers a tech, sometimes one, or both of the other players recieve a gift of similar tech, but one level lower.
For instance, when I researched magneto missile drives, the other two races got ion-pulse missile drives as a gift.
Now, I discovered ECM-3, and 1 of the other races got ECM-1 as a free gift.
This happens automatically, no player input involved.
WHile it is all nice and friendly, to share some tech with friends, it is not the way I envisioned relations between the nations, RP-wise.
Not for nothing did I set their relations to friendly, and choose not to have a research pact.
Any way I can prevent this free flow of technology, other than maybe SM-ing the racial views the nations have of each other to be much lower?
