For a while now I have had the feeling that I was missing something and today, while playing GOTM 4, it hit me: I am no longer able to trade communications! 
It used to be a major source of income in the early game, and an extra incentive for early exploration. Something must have happened to communications trade somewhere between my first civ III games and Conquest with the lastest patch. What was it? Is it completely gone? Is discovering the laser now a requirement? Can someone enlighten me?
