Hi 
I am playing on Regent. I built the GL.
I had contact with one AI but completely destroyed them before the GL or contact with any other AI. I now have contact with one more AI. I am behind in techs. My advisor confirms this. I was ok with it as I knew the GL would help me catch up.
So far even though I am 5 or 6 techs behind the only AI I have contact with I have recieved no techs.
My question is do I have to wait until I have contact with another AI before I get the benefits of the GL? Do I only get access to the techs that have been researched by the AI's I have contact with or all AIs?
Thanks in advance!
