Spys are to limited.
CS - Influence (Yawn)
Other Civilizations
Steal Tech, Thats all - as far as I know
I think they should introduce more options for the spy's.
Blow up a building - This would be fun, could cause massive unhappyness
Sabatage - a wonder in the building queue - so it takes them longer to complete and gives you a change to build it before them.
Assassination - of Great Artist, Musicians, etc
Cause Unrest - Chance of a city flipping
Framing a civ, could cause unhappiness, start a war, break an alliance.
Steel Gold
Steel Artifacts
I'm sure there are many more things the spy can do.
