I like that mission as a way to train my spies before moving to sabotage\ stealing great works. I hate when they steal my great works or sabotage my production. A defensive spy sometimes help. In some games my spies do as they please. In some they are useless. One of the unknowns of the games.
Freakin' Joho tried to steal a greatwork from St. Pete's. Obviously I denounced him straightaway, but still, what a complete d---. We had DOF'd. Luckily, my Soviet KGB killed the thief before he could escape. Hadn't even made a spy yet.
First time I'd seen someone go for a greatwork. Its always been gold or production before. Better be more careful with my city planning now.
It seems to me, at least in week 1 of the game being out, that the gold mission wasn't per turn. I'm fairly certain I took a X gold hit all in one turn from a spy.
edit: If its per turn, how are you supposed to keep tract of that? If you're making 2k gold a turn, its coming from quite a few different sources, including foreign trade. If you have 50 trade routes and 50 cities, 22 civs in the game, lots of deals, well, the number ebbs and flows every turn. I'm sure it doesn't say on the info panel: " - 32.4 from spies." Or does it? Should I be doing the math every 10 turns to check? Is the math even accurate? With so much missing info, I wouldn't be surprised if not every debit was listed anyways.
edit 2: Anyone have a good way to predict which cities will be targeted? I've only been hit by spies 4 times I think, capturing two. 2x it was my capital, 1x it was another city's commercial zone, and another time it was a random city's industrial zone. Again, with 50 cities, its going to be pretty hard to catch them if its random.
