Espionage in Civilization 4 works pretty badly. There must be ideas out there on how to better make use of spies and Espionage. If you have ideas or thoughts, just publish them here and we'll consider the possibility of making something up to make espionage in Fairy Tale better. I was thinking about making spies able to see each other and also fight each other, but I don't know if it's a useful feature. It may prove to be more an annoyance. It would be a rather fun feature to try and maintain an effective spy-network in some way and intelligence system in the times of peace and make full use of them during wartime also. Not just poison watersupplies or crank up the espionage lever to light up the rival towns.
