Espionage re-revisited

[anarres]

Spys actually have a better chance than a diplomat (i.e. embassy) when you steal, and you don't need to be at peace to use them.

Of course you need to research Espionage and build the IA, so it's not "easy" to do.

@krys: counter-espionage? I assume you mean 'expose enemy spy'? It will try to find an enemy spy and you have a certain rate of success on that.

There's an excellent article on spying on a site I visit occasionally: http://forums.civfanatics.com/showthread.php?t=97042. I have seen no evidence indicating that MP works diffeerently, except for the obvious lack of info of failed attempts (as we see in other cases as well).

"...on a site I visit occasionally"

Aggie, even though you don't post there much now I think we are all aware of CFC and your part in the community there.

There are a lot of bells and whistles available with spies but just a couple are usefull imo:

No risk of detection:
- Investigate city (typically ranging from 35 to 250 gold)
- Full overview of opponents troops in F3 (for free once the spy is in place)

Risk of detection / failure:
- Steal plans (get exact locations, experience and damage of every unit of opponent)
- Steal tech (speaks for itself, can be very powerfull if catching up, allows tech of choice if no failure)
- Expose enemy spy (if you have to hide something)

Less usefull:
- Initiate propaganda (which is basically useless since even a little culture is enough to prevent it on the higher levels)
- Steal Worldmap (only has a purpose in the rare occasion you don't know the map at that stage of the game, the KR rightclick method provides similar info for free if you know the map)
- Sabotage Production (the more shields in the improvement the more expensive it gets. Talking big bucks for Wonders, Spaceship components and nukes).

I'm quite a pbem-noob, have very limited experience with spies. I've built the IA only once; didn't perform any mission other than planting and that was just to observe my opponent on F3.
The 'expose' mission has certainly something to it in a PBEM, but it's rarely used in SP (if at all; never used it succesfully myself).
In some SP, an AI succesfully exposed my spy while their spy was caught in the act as well (which is different to the steal mission: get caught=no success).

If you perform that expose mission and assuming your opponent has indeed a spy in place, then
(i)-your spy will always be used up in the process whether succesful or not
(ii)-your spy could be caught if mission was succesful (OR: your spy could get away if mission was not succesful)
?



(i) may sound silly, but I see some logic in it. If a spy was succesfully exposed, the victim would never know if the rival has an actual spy or not (i.e. if replant happened afterwards or not).

I guess you bunch have used the expose mission a lot.
So what's the deal?

[anarres]

Hmm. Maybe Aggie will know, but you will probably have to email him to find out.

[Grille]

Tested a bit around. The sample was way too small, but big enough to tell that (i) is mud.
The first part of (ii) seems to be correct.

If I understood Oystein's findings correctly, success chances are always 80%. Then the risk option influences the chances of getting away. I asked Oystein for confirmation on the 80% thing.

Interesting: the price of the plant mission is cheaper than the cost of the expose mission, so maybe it's worth to expose at high arrest-risk and then replant afterwards; haven't crunched numbers/probabilities, though.

From the tech leader's perspective, the removal of the enemy spy could be achieved cheaply, compared to the investment the crook has to make until having the tech. Then again, it's hard to tell if there is indeed a mole unless the tech steal already happened (no mole=100% fail).

edit:

quote:
2) Use Expose Spy frequently, although this requires your own spy (and costs money, although the cost is fairly minimal). This means your opponent has to plant a spy successfully before they get a chance to steal.

if you want to expose frequently though the existence of the enemy spy is pretty much unclear, you're probably better off always picking the 'immediate' option on the long run.
That is, of course, if success is indeed always 80%.

Sorry if I'm missing the obvious, but what is the "KR rightclick" method? I don't recognize the abbreviation.

[Kemal]

"KingReno" ((KR) rightclick method, which means right-clicking on visible map tiles to see, based on the info it gives on the productivity of the tile, "invisible" improvements made on that tile.
