syncron09: I tested this by moving a unit out of a city deep into my territory, I had all the areas covered, on the look out for enemy scouts. The very next turn the AI sends a unit towards that city.
Just out of curiosity, isn't this exactly what a player (AI or human) should do to see into a city and check if an army is laying in wait? You said the AI sent a single unit. That unit is by definition a scout. In all strategy games involving fog of war, scouts are extremely important and the AI sending a scout is a smart AI not a cheating AI, isn't it?
Also, from a return on investment point of view - Sending scouts who happen to take over undefended cities to acquire resources for a turn or three is worth losing scouts. It's super annoying and pays for itself with ease. :-)
The original poster was actually asking about AoW:SM which did have "cheats" such as the AI being able to see concealed units. This was fine since the AI was stupid and needed the help. Since IBM Watson isn't our opponent, giving the AI production bonuses is appropriate for AoW:3.
