I've had 2 games in a row now that the iconians failed to do much. They actually claimed a lot of planets, but most of them have nothing built on them. This could be a valid strategy to a point, but once the colony rush is over, it's just silly.
What was funny is at first I thought they had changed espionage. I'd go to plant a spy, and I'd see no where to put him, and no buildings. I thought maybe they'd changed the counter-espionage building's effects.
It was only later when I started invading I saw that there was nothing there...
