The Hall of Players

[Seraiel]

This is scam, Viccy just trade Gunpowder against Constitution with Mansa, I didn't trade because usually doeesn't trade a tech that's almost twice as cheap and pays the difference in . 400 lost through a misclick, 800 lost because of hoping Mansa would drop WFYABTA because it was only 1 tech and because of not realizing the risk between Mansa and Viccy trading and now 600 lost on pure cheating of the AI. When the AIs + Deity was coded, the DEVs really overdid it. I'm glad that there is a difficulty that is so challenging, but sth. like that is laughable imo. . Viccy had no available via trade, so the the AI is bunkering for whatever reasons but doesn't trade towards the player is available for trade towards another AI. Handicaps are ok for me if that is the way to code an AI that can compare, but when a player isn't even given the same chances it makes me angry. It's the same with AIs trading Iron against Corn while demanding 150GPT for it from the player. Against the last, the player at least can still do something by trading a resource with the GPT and then pillaging the resource but if the DEVs had wanted the AIs to play in team they also could have made it like that from the start imo. .

It'd be so easy to make a CIV6 that's better than CIV4, simply take CIV4, fix the bugs and improve the AIs so they're aren't unfair and are therefore more intelligent so that they could do with less bonuses. It's the wish of every player that a firm simply releases his favourite game in a new version, the developers of DAoC are doing so with the upcoming Camelot Unchained, will Fireaxes be smart enough to realize that they could get millions for listening towards the players? They'll surely think "yes, we could be smart and get millions for something we already programmed, but we're smarter and will get bazillions for offering the player something that is better" . Maybe Fireaxis is also simply controlled by RNG ^^ .

It's the same with AIs trading Iron against Corn while demanding 150GPT for it from the player.

This is very frustrating, and you saw the screenshot I posted somewhere recently, where the AI demanded 128gpt from me for iron, but traded it away for 'free' a turn or two later in return for sugar. If the AI demands "the princess and half the realm" of the human for valuable resources, it should do the same against other AIs.

It's a great game, but some 'features' can be extremely frustrating.

 

[Pangaea]

Maybe Fireaxis is also simply controlled by RNG ^^ .

Heh. They'd be out of business by next week

 

[Seraiel]

I know this is a very minor point with regards to your concerns.
However, maybe you should reconsider the above. Your choice seems very strange to me.

Is there any way that Mansa's land tiles will benefit you more than offshore cities ?
I'm under the impression that only a select few World Wonder cities can beat offshore ones, if you're looking at "science output / land occupied".

Also, if you're going for Corps, which I assume you are, you're also forgoing Sushi resources and will have to resort to buying them.

Right ?
Also, if he's teching so fast, why not keep Mansa as a trading partner until the very late game ?


On the tech speed :
I doubt BUFFY .004 matters at all.
The Tiny map could factor, however. It could mean that the AIs will produce less settlers and start growing their cities earlier. I'm not sure that this reason alone would be enough. Island cities matter, too.

The AIs got no island cities except that Big & Small is basically one big island and Viccy started on an extra continent so there are intercontinental TRs. Mansa ran away in the Terra game aswell though and he already had GNP way higher than I know from him before the WB that Viccy sent met us. And Idk. , but how does Tiny map factor in? Both games were on Tiny maps, but I'd consider research to be slower on Tiny because of less cities in general. Anyhow, this cannot have been the deciding factor aswell, because Mansa's GNP were too high already when there still was land to expand to. You saying that you don't assume BUFFY .004 to be the problem though I accept, as you've more experience with the latest BUG-mod than I have, I only have 3/3 games in which Mansa researches on a level that is beyond what I know from him.

And yes, island-cities take less land so they're valuable because one can have more cities, anyhow Mansa's cities are size 15-20, he has the islamic shrine and he also has resources that I need (i. e. Bananas, resoures are enormously important in Corporation Space Races, more important than ) . Mansa is giving me WFYABTA already so I cannot trade from him anyhow, I have Roosevelt on friendly though and Viccy is on her way towards it, only need +1 more favourite civic bonus, which is the good side of her trade Constitution for Gunpowder from Mansa .
I also need enough cities that can build Spaceship-parts and on Tiny this is not easy, Mansa's cities are all continentally locked ones and they even have rivers (-> Levee! ) .
That and + I hate him .

I'll post a nice screenshot soon btw. . I own the only sources of Marble and Stone, something really good about the map. It didn't hold Roosevelt off building the MoM a few turns ago ( ) but I got the Mids somewhere like 400 BC and will get the HGs next turn (I believe 50 BC ) . Those are latest HGs I've ever built in a Deity game. 500 BC is late for the HGs to go, but 50 BC with 15 cities is really hillarious .
The last supports my point of view, that AIs aren't likely to start building the more expensive Wonders at all when they lack the corresponding resource (even on Deity) ! I really was astonished that Roosevelt built the MoM as it's not cheap, there are so many Wonders left that some will obsolete before they'll be built (i. e. the Hagia Sophia) . I have reason to keep believing that there are AI wonder priorities btw. , though Tachywaxon or someone else told me that he / she didn't find any code for that, because the AP went very early, and we know how expensive that one is. I bet that the sistine Chapel will also go at some time and that without the AIs having Marble which I may trade to them once I have the NE (already got the HE) .

 

[Seraiel]

It doesn't account for the GNP but Tiny map = tech discount.

You mention Mansa's land being all green and riverside...
... Your own land seems very brown...
... maybe that's part of the reason you have a hard time keeping up ? (excluding wonders, trade routes, city sizes and stuff)

Is there a special map-discount for the AIs the smaller the map? I still remember the techs on Standard / Normal / Prince costing the same as on Tiny / Normal / Deity, so I think the costs of techs are bound to speed and not to map-size. Bulbs get stronger the smaller the map, but the Wonders i. e. also have a certain cost because it's Marathon or Epic, not because it's Tiny or Large.
Regarding the Sushi-resources btw. : Sushi-resources can usually be very easily traded, I therefore mostly care for Mining-resources. I'll found 4 island-cities in any case because of the oversea's TRs but not more probably. Still thinking about that island with 10 Jungles for the NP. Not too fond of B&S for Spaceraces yet, the maintenance is horrendous and not being able to settle cities that have Forests left in the end doesn't also mean that one cannot chop out Spaceparts which is a big thing with not being able to 1T the life-support, but it also means 1 GP less probably.

I wanted to post this for you btw. , a screenshot that really goes towards my heart:



HGs 40 BC and jumping from 3rd place (4th only 20 or 30T ago) towards the 1st .

GNP and tech-situation mostly under control again:





I'll get Oxford in a handful of turns (unfortunately no BC Oxford but close ) , so my research will rise by 80 bringing me up to almost 500 / turn. Not the most ever conducted on Marathon, but with a non-Incan / non-Persion / generally non-UU and or FIN leader this is quite ok imo. .

Regarding me having research-problems: @BiC: It's not me that has research-problems, it's Mansa conducting crazily high . See the list I posted a few posts above, GNP like in the three BUFFY .004 games I mentioned are not normal:



As you can see I'm conducting a lot more / turn in that game because I already have conquered the whole map (and because that means more cities because it's Small and not Tiny) , but Mansa has (about? ) the same number of cities as he has in my current game and his GNP are 400. In all fairness I also just looked at the GNP from 1 AD in my GM-137 game and the GNP of the best AI in that game is almost compareable towards Mansa's current GNP, but know that GM-137 was on Large, this is Tiny. Mansa's nice land may be part of an explanation but it is absolutely uncommon for GNP to be that high, even on Marathon (especially three times in a row! ) .

 

[Seraiel]

@ BiC:

Afaik GNP is everything that can be created by the slider so , , or . I'm not really sure if also plays a role and if everything is 1:1, it should be, but when I just tested with a Spy-Specialist which I set towards a coastal tile I lost 2 and 4 but the total GNP got reduced by 7 (may be a rounding error but may 3 (or 6 because I am PHI? ) are also 1 GNP) , I believe it's really only everything that can be created by the slider though. You can i. e. see if there are CRE civs in the game when checking the GNP via the demographics at the start as those have at least 1 more GNP at turn 1 (exception: A civ has an Oasis in the 9-tiles-square) .

With the maintenance mattering towards the GNP it's actually even less explainable why Mansa had / has so much GNP now, because I'm playing with cylindrical worldwrap so distance-maintenance = 1.5 of flat, and Mansa has relatively more cities than i. e. compared to GM-137 where he had almost compareable GNP at 1 AD.
Regarding the slider: Higher sliders only then have a higher GNP if a civ has multipliers, without it's 1:1.

Regarding counting the GNP: I may do so but will wait 2-3 days for an answer of the BUG-team if they could imagine something like that or I may also play a 4th game to see again. As it looks I'm not gonna get a #1 with Frederick anyhow, it seems Chariot or Axe Conquest is needed at least to really break the 1265 AD win of ShannonCT, maybe HA can also do, but not sure as I got Construction extremely early because Mansa beelined it after, maybe I just cannot imagine how much happens in 180T of Marathon. Maybe it's also only me not getting the MoM and getting 2 Great Prophets that'll not make me get the #1, I play very carefully though because the game demands it and it's a really good game. Hopefully the EQM-formula will at least value it with 70-80 points.

Regarding the last: I don't know what you mean with relating towards the score. It may be that Mansa simply has better developement than in other games, his cities are size 8 to 15. If you still mean that my empire is the problem: Yes, my cities are very small and I got some brown land, but I got good reasons for that, the biggest being that the maintenance is so high and that my Courthouses are so cheap that I whipped them in all cities, the other big one being early Oxford. Both directly affect the GNP of me and it's really not me doing badly, it's the opposite, I play a strong round imo. , I very seldomly am able to take 12 cities with only losing 5 Catapults and with only producing 16 units in total, it's also the first time at all that I'm able to keep up with an AI exceeding three times my GNP and the biggest advantage is that I got the only sources of Marble + Stone so I could build the Mids and the HGs so late .

And thx (for the link aswell as commenting on the HGs, it really was a great relief once I knew that I could whip them in case of an AI getting a GE a few turns before they were finished normally and getting 15 population really was a very large push, so it really did feel great . It maybe was a little similar to when you attacked that one city with the HAs today and had 4-5 consecutive withdraws when it really matters ) .

 

[Seraiel]

Addition:

GPT via resource-trades are also added towards GNP, that's why one (usually) has a positive GNP during Anarchy.

 

[Seraiel]

Oxford 70 AD and the GNP-problem at least seems to be solved from the side that I have too little ^^ :





Mansa asks on the same turn for my only monopoly tech .



The last is also something that AIs can do that the player can not, ask for a tech that the player would never be willing to trade ^^ . One should be able to set a diplomatic stance towards an AI like the AI also has towards oneself. If one is furious the AI is building more defenses but makes less stupid demands that cause negative diplo and if one is furious the AI is not willing to trade military techs towards one. The stance can only be changed every 7-30T or so. If one is friendly towards an AI it'll ask for help any turn and trade all techs while not building any Castles .

 

[Seraiel]

This is really annoying. Just when I think I have the round under control one bad thing after the other happens. First, Roosevelt makes peace. Then Viccy trades Military Science towards Mansa, she doesn't care that he DoWed her, she's cautious towards him. Mansa now has Military Tradition + Horses + Iron which he gets through trade which I still can't see but this means that he has Cuirrassiers and he upgraded almost all non-LB-units towards Grenadiers. With his cities having between 40 and 80% cultural defense that's a heavy hit.
Before, Viccy traded Chemistry to Mansa although she was the only civ that had it except me, this brought my gold-losses through AIs trading a tech before I did or in this time even could to 2.5k in this round.

Take a look at Mansa's power-graph:



I whipped Cuirrassiers in my HE-city like a madman right before, it has +7 whipping anger, I was so close before being able to attack him and I could have taken 3 cities on the first turn of the war and another one only 1T later, that'd have destroyed him completely! Now it seems that my only chance is to trigger the GA from the TM to switch to Police State + Theocracy but even with whipping my cities completely into the ground (which I ofc. like very much during GAs -.- ) I could only get 30 Cuirrassiers, Idk. if I should wait for Cannons or not. I'm short before simply risking it and attacking him with as many Cuirrs as possible but a Gren with 60% culture, 25% stationary and Combat 1 is STR 24, twice as strong as a Cuirrassier, I believe double strength means 1% chances to win so probably useless. It gets a bit better with promotions because my Cuirrs have 5XP+ all so the Gren would get reduced to something like STR 19 while the Cuirr would have 13.2. Sti, maybe 2:1 would break through but then I can only assault one city...
So Cannons and slow slows slow or Cuirrs and risking to lose the round.

It also seems like I imo. must attack him now or never because this is what happened to his GNP right out of nowhere:





How is this even possible? There were at least 10T peace and he was at 980, I was at 700, that's ok but then he gets +30%??? From what? He didn't build the SoL or so, he settled no cities, nothing except normal growth happened, this is impossible.

The only good thing I still have is that Viccy is researching Replaceable Parts and Roosevelt is researching Scientific Method while have enough money for 2/3 of Steel, but then again I cannot trade with Viccy because Mansa getting Cannons would enable him to upgrade those 10 Cats that he still has towards them and then I'd be completely lost, so I need to cripple him towards the point where he doesn't has them anymore in about 20T, because then Roosevelt will have SM and then I think I need to trade at latest .

This is the current tech-situation after Mansa even traded with Roosevelt, Mansa doesn't mind that Roosevelt DoWed him two times, he's annoyed and that's still not enough to make him stop trading:



Just one very honest question towards all of you: Is this normal that one needs to play more than a 2nd game to get a good game on Deity? I didn't have this situation yet, normally I play 1 game at most and then get a #1 or 100 points EQM-game in 2nd try.

 

[Seraiel]

I'm planning to take out Mansa via Cuirrassiers with using Spy-revolts. I'm going to trigger the GA from the TM and switch to Police State + Theocracy and whip out 1-2 Cuirrassiers in all cities. Right before I'm going to whip out 9 Spies so I can revolt 3 cities of him. I'm going to attack all three on the first turn of the war and thereby will reduce Mansa from 7 to only 4 cities. This should cripple him badly and if I have 30 Cuirrassiers I should be able to easily take the capital after a cease-fire and when I got the Spies into position again. This might get really interesting so I'll make screenshots and post updates .

Plz don't forget the question that I asked and answer it honestly. I know that one might need to start 2-3 games to get a decent one on Deity but is it normal that Deity-AIs are so hard that it's needed to play 3 or even more games to get a 100 points EQM game or even a #1?`

Tia.

Progress report:

This was the first that happened after I had made the plan to Cuirr-Spy Mansa:





Sometimes I think AI recognizes what the player is thinking / doing.

This city btw. is one of the main reasons why I cannot let Mansa live, my NE-city getting crushed by Malinese :



Notice that that city is making 22 :culture / turn and that it has not even 50% on its centre tile?

This is how my buildqueues looked after switching in Police-State + I added a Cuirrassier in the capital aswell after making that screen:



This was what happened to the power-graph 1T later: ^^



I must have awesome luck in the war with me having this luck when only 2 Spies had reached each of the cities and had been in enemy territory for only 1-3T:





I really wonder which date I will achieve in this game. Mansa went Communism so he's gonna steal the Great Spy from it after he already stole Liberalism and Viccy stole Music + Economics + I got 2 Great Prophets so 3 GPs missing, 2 GPs = crap (had the awesome luck to get the free Academy event though, otherwise I could have given up this game) , not getting 1 GP probably following beause I'm currently destroying my GNP and not even have SM and 1 free tech missing aswell. If my finish-date will only be halfly competetive I'm gonna laugh because the game I'm trying to beat was played with Incans aswell.

And as a last, a preview of the troops I'm going to expect:



Not bad for someone who has a unit-build-ratio of 4/10 and is regarded as a peaceful techer, right?

 

[Pangaea]

I must have awesome luck in the war with me having this luck when only 2 Spies had reached each of the cities and had been in enemy territory for only 1-3T:

If you checked out the AW game in S&T, this has done my head in too. I also lost a spy en route to a city, the same turn it entered enemy territory. Stacked spies in a city to steal techs, and lost practically a spy a turn until I just had one left. Ridiculous stuff. Sometimes it feels like the AIs have a spy on every tile on the map.

Good luck with the war. Grenadiers can be nasty, but thankfully Mansa doesn't have Rifles. Cuirs against Rifles is not a fun experience

Thx for this post Pangaea . I'd not attack Rifles with Cuirrs again ^^ . I once did in a game in which I didn't expect the AI to get Rifles and destroyed my whole economy with whipping to win faster so I couldn't research anymore, then Toku got Rifles during the war, he had beelined them even before it... I think I lost 15 or 20 Cuirrassiers to a handful of them. I had a very small chance that I could still win that game because I really had a huge army but Toku showed me something different. I accept that PRO Rifles aren't beatable by Cuirrs since then.

Cavs against Rifles btw. goes interestingly well . The Cavs can have Pinch with the 2nd promo while the Rifles won't have Formation giving the Cavs an advantage, then the 30% withdrawl and with Airships I experienced 50% survival chances for Cavs against Rifles. Should be even more with Spy-revolts so those units, though the Rifle is the anti-unit to the Cav are equal if the Cav is the attacker .

Progress report coming, took 3 cities on turn 1 of the war. Almost would have had a rage-attack. Mansa was very funny again .

 

[Seraiel]

Mansa got a GE in 390 AD and Roosevelt got a GA.

Now if you think that Mansa would be so nice to build a nice Wonder for me (sixtine C. and the University of Sankore would have been available aswell as the SoL) , , Mansa knew what would come and built the most useful wonder possible:



Versaille in a city that's close to my capital but that is even closer to his . Mansa.

Roosevelt btw. used that Great Artist against my only border-city and ofc. not against Mansa's capital that is crushing his silver-city completely... . There must be sort of a script that the AI tries to target the player preferably, because I really made only little border-pressure.

I was interested in the graphs, this was what happened to the score after the build-up:



I dropped so heavily from the whip that I even had the underdog bonus with Viccy in between, and I was on 1st place before XD .

The power-graph at the end of the build-up:





37 Cuirrs in a Space Race against a 7 city AI

Mansa kept on annoying me, he's really the worst AI that I ever had XD :



I then switched to Caste + Pacifism like usual in a GA. Take a look at my unit-maintenance :



The GNP before the war:



The tech-situation:



Ofc. Viccy had to directly trade Replaceable Parts to Mansa so I won't get it from her for Scientific Method which I get from Roosevelt... I wonder if any of you ever had a tech-situation that bad so late in the game (and just think of that I only lacked Guilds + Engineering when getting Education... ) .

Now the important part:



Aaaaand...



*rage attack*

3 Spies in that city got discovered and 2 more weren't able to trigger a revolt so 5 Spies lost for nothing! I could have had 2 Cuirrs for the same price!
The next revolts went without too many problems though, lost two further Spies so 10 Spies lost for 2 revolts... It didn't go all that bad though:



:x

I then attacked the city without a revolt, 2 losses .





Moves like this I like the most:



Capturing a Worker that I cannot defend with a 3-move-GG, delete the Worker and retreat into american territory (Mansa has no open borders with Roose) .

Next city:





And 3rd city:





Curious how many Cuirrs I'm gonna have left after the war with so little losses XD . Keeping more Spies probably would have been more valuable though, because I still need to steal at the end of the war and maybe I can steal a tech from Roosevelt later aswell, but don't know, atm. I'm mostly ok with how the RNG decided this time.

Mansa's response (I wanted to check if I could get a cease-fire, but I think it's not possible on T0 or I would have needed to destroy even more of his troops) :



Found something nice towards the end, look at the XP of Cuirrassier 2 (Hamburg) XD :

 

[Qactus]

...

...

Iirc stacking multiple spies on the same tile makes them much more likely to get caught, but I don't know how big that penalty is.

 

[Seraiel]

Iirc stacking multiple spies on the same tile makes them much more likely to get caught, but I don't know how big that penalty is.

I don't think this is true because I lost about 1 Spy / turn and had 9 in enemy territory and read that the base-chance is something like 10%. It might be lower though and the penalty can't be very high, otherwise espionage victories would have a real problem with the Spies needing to wait 1T before the Spread Culture Mission becomes available.

The real problem is that the Spy-missions sometimes have too low base-odds, 55% for a city-revolt is not acceptable, even with 3 Spies the chances of failure are still 5%. And I think the AI really has Spies in all of its cities later, because this would explain that one doesn't lose many Spies in an espionage victory. Security Bureaus also seem to be a great problem imo. . I really think it's that the AIs has Spies on many tiles, because one usually gets instant spied when declaring war or when an AI becomes annoyed, and I also played several time victories in which I sabotaged the AIs building SS-parts for a long time by only spying in the nearest island-city (map was Archipelagio) . Only very rarely some would get cought.

I own the world record for the most negative diplo by espionage btw. with Bismarck once having had -4xx through discovering my Spies in a time game in which I built over 2000 Spies ^^ .

 

[Seraiel]

Mansa counter-attacked my wounded troops at Djenne. Had luck and won 1 37% fight and 2 50% fights only losing 1 Cuirr to a Pike (63% for Pike) . Interestingly my Supermedic didn't defend though but the Combat 1 Cuirrassier did?



Great luck, if I had lost the Supermedic that'd have been a holdup of at least 1T on the capital and the war weariness got really bad because of:







The next city:







The RNG with me, winning one 30-70% battle after the other and Courthouse + Forge surviving. Having 37 Cuirrs showed to be a little too many with so much luck but I'm still glad I had so many because otherwise I'd need a lot longer for the war.

Bananas reclaimed:



The graph I like the most:



And I wanted to post this in the last post already, Mansa's GNP finally have become acceptable XD :





Steal 460 AD:



Now Viccy doesn't trade anymore with Mansa, like that I'll get the Kremlin because he's the only one having Communism and I don't think he'll be able to build it ^^ :

And Steal(ing) :



I calculate that stealing Mansa's whole gold will cost me about 2k espionage in the last city. Therefore this revolt is a little too expensive and I attack his capital, an 80% city without it:









4 losses *lol* .

Corn reclaimed:



XD





Lizzy didn't even have Longbows, so everything above an Archer or an Axe was Mansa. Nice stats (11 losses) for so many kills :



The lol of the round. If someone can explain that city-placement to me, then I'll hand him a price. AI is scripted to not settle too close to borders, yes. And AI prioritizes , yes, we see that both :



Last city for the moment...



... because I need to steal gold and would have too much unhappiness if I stayed in war.





Need Sushi -.-

 

[Seraiel]

It's done, Mansa is dead and I'm going to win the first game ever in which an AI exceeded 3 times of my GNP and that even for a long time :

Mansa is a cheater (imo? ) : Look at his GNP, 75 from this city!





He can work 14 water-tiles at most, that makes 43 GNP at most for me. Now assuming a Library, a University and an Observatory he can conduct 75 BPT! When I captured that city it only had a Granary . [EDIT] He also needs to build Wealth to compensate the maintenance. Sry, but Mansa is cheating, see this as the hardest proof possible with BUFFY.

Getting on par in the tech-race. Physics wasn't researched yet and I even have a Great Scientist so at least I'm gonna get that free GP .



Stealing Mansa's . That trick discovered by Pangaea where to set the onto the war-target and then steal all of his from the last city is pure .







The Last Survivor of 12 curageous Spies .



Eternal peace and tech-trading :





Some fun:











Thx for everyone reading and participating after my initial post. Plz don't overlook the question I asked.

 

[Qactus]

Iirc stacking multiple spies on the same tile makes them much more likely to get caught, but I don't know how big that penalty is.

I don't think this is true because I lost about 1 Spy / turn and had 9 in enemy territory and read that the base-chance is something like 10%. It might be lower though and the penalty can't be very high, otherwise espionage victories would have a real problem with the Spies needing to wait 1T before the Spread Culture Mission becomes available.
...

I looked it up, here's an old thread on the mechanics: Spy detection . It contains all the relevant formulae, but also some helpful interpretations such as the following post:

...

The basic chance that your spy is caught during a mission is a value between 0% and 25%. This chance is dependent on the total amount of espionage points produced by you and your target civilisation.
An enemy spy or the security bureau present in the tile of your spy increases the chance of being caught by 15%.
A counterespionage mission performed against you increases the chance of being caught by 20%.
When one of your spies has just moved or is on the same tile as another one of your spies, then it has a 15% increased chance of being caught. You thus usually will want to wait at least one turn after arriving on a tile and having multiple spies on a single tile adversely affects your chance of a successful mission. (There is also a cost reduction for waiting on a tile for up to five turns.)
These chances are summed up meaning, the chance of being caught during a mission is a value between 0% and 75%.

These percentages are then multiplied by the mission modifier which is equal to (100 + difficulty modifier)/100. This means that the Counterespionage mission will always succeed and that the Poison water supply mission and the foment unhappiness mission only have halve the basic chance to fail. However, the switch civic and switch religion missions have a 1.5 times as high chance to fail, a value between 0% and 1.5*75=112,5%. Thus when your opponent has defended itself in an excellent way, then these missions will often fail. Usually, there will be a few cities which are vulnerable enough to be targeted by these missions successfully.

I hope this helps those who have troubles with the earlier mentioned formulas. (Also see post 5 for the chance to be captured while residing in a tile, doing nothing.)

 

[Seraiel]

TY for the link and the information that you found . This will be very helpful in future games.
