I belive, simply by clicking on an empire, you can see every resorse/ researched techs that you have not researched yoursef is far to powerful............... perhaps alliance member info should be shared?


with the new paction are spies, if you want to know/possibly trade a certain resource/tech it should cost you time/resources/dust  or a spy mechanic of some type.  (kind of along the lines of Impirium galactica 2 spying, but include resorses as well)



kinda like my idea long ago, when i thought that just showing the info right off the bat was better than waiting for the game to think evertime you clicked on a resorse.
