Hi!
Stealing tech when invading...is it random?
End of quote
I've looked into that in an early DA version. I'd say at that time it was semi-random. When I reloaded the turn and reinvaded, I mostly got the same tech with the invasion, and that was not dependent from what planet I invaded. But in the next turn I quite often got some other tech. And the probability for obtaining the tech had decreased, so after about 8th invasion I practically got nothing at all, despite AI HAD techs I didn't.
At that time it looked to me like the game had each turn a set of available techs for invasions, and that set was decreased with the number of invasions. Since then it looks like developers have put some work into this, because top techs are rarely obtained, on contrary to my previous experience. Or is that just the effect of me nowadays playing on suicidal? Can't say for sure.
