Well just before I say anything all I want to say is I really like the spy addition to the game. Now things that I noticed if you don't send any spys out to other civs, you never have to deal with their spys on your worlds. Now this happen in my 3rd game but it might not always happen this way. In my first game at most I had 60 spys on my planets and at the end it was decreasing but it was at 39 and lol my economy, starship building and research were always being attacked by spys lol, I actually had to worry in mid late game cause my economy sometimes droped in the hole but in just plain old GalCiv2 than never happened... I actually kinda liked to having to worry about more things in the late game. Someone else want to see if it true that if you don't send spys you will be safe from spys.
