This is definitly a noob question
I am fairly new to GC II TA and have not been able to figure out how to passivly spy on a nation. I understand how to put spies on planets, but not how to put spies on a civilization in general. I understand there is probably a very obvious answer to this, but it has been driving me crazy. The more specific you could be the better.
Also, I've never played a very long game, but how to do assend as a civilization into a super civilation where you are really good at military or commerce, etc. Any advice is greatly appreciated. Thank you.
