probability of events

[ksa76]

I have read through the random event list, but it is still unclear to me how exactly the event and quest mechanics work and in particular how I can increase the likelihood of getting certain events and quests.
I have my assumptions, but hopefully I can get some definite answers to the following questions.

Q1) Can the AIs get the same event or quest, once you have gotten it first (or vice versa)? For instance, can more than one civilization get the marathon runner event (free golden age) and the federal reserves event in the same game?


Q2) In the random event guide it states that there is a chance of 1%/2%/4%/4%/6%/8%/10% per turn for any event to occur (era specific Ancient/Classical/Medieval/Renaissance/Industrial/Modern/Future). Does this probability mean for your civilization in particular or it is a weighted probability for all remaining civilizations in their respective eras?


Q3) Is it the gambler's fallacy to assume that the probability of an event happening somehow increases if you did not receive an event the last turn?


Q4) Is it an undeniable fact that you cannot increase the likelihood of getting the" colliseum quest" or the "musket man quest" by preemptively building a colliseum or a musket man?

I have never seen the ai complete a quest, so i dont think (civ4 gods please correct me) that the ai can recieve quests.
Q2 is not relevant if the above holds true.
Q3 yes, its a gamblers fallacy. Each turn the game will roll a random number, if it is below the quest chance, wallah, you get the quest. Previous turn has NO bearing
Q4 yes, it is undeniable.

Actually AI can and has completed quests. Most quests have the "you will have failed" section and in all of them the first thing it says is if another civilization completes it first. This has happened to me in the past when I first started (I'm better now so it only happens if I don't care about the quest).

 

[neilmeister]

But that is different. The quests arent global, as in the first to finish gets xyz, but rather the players either wins or loses the quest. So if the player 'loses' the quest, it doesnt follow that the ai 'won' the quest.

Thanks for your responses. It seems a bit unfair for the AIs if they can't receive quests.
I am still a bit curious as to see what others have to say on the event questions.

I'm sure the AI gets quests. I've seen it announced that an AI got the herbs quest, for example.

I think we need to distinguish between events and quests. The herbs event is not a quest. It is true that AIs receive events just like the player. The question is whether they can also receive quests, as Neilmeister pointed out was not the case.

Sorry I should have said that I've seen the AI complete quests. Most often the Horse Whisperer one since I usually don't rely much on cavalry. So yes they can fulfill quests.

Interesting. Would that not make quests global? If so, I still need answers to my first two questions.

Q1) Depends on the event. Some are unique per game, some can be repeated (e.g. forest fire, mine accident, airplane crash, etc.).

Q2) Global setting, should affect all civs.

Yes QUESTS are global. EVENTS are not and can happen several times (sometimes more than once for the same civ).

 

[neilmeister]

Well, I eat my words. Sorry for the mislead.

Quests are not global. They can happen for each player. The "Done" event trigger for each quest is global, so only one player can complete the quest.

The one exception is the Corporate Expansion quest. This one is set to be global.

As far as I know the AI does not ever pursue quests, but can complete one entirely by accident. Particularly the build X of building Y, or build X of unit Y type quests.

You can look at the XML file to see this for yourself. The relevant file is CIV4EventTriggerInfos.xml, located in the game's Assets\XML\Events folder. The triggers for the Blessed Sea event (put colonies on way too many land masses) are EVENTTRIGGER_BLESSED_SEA and EVENTTRIGGER_BLESSED_SEA_DONE. For the also unpopular "Find and settle near the Holy Mountain" quest they are EVENTTRIGGER_HOLY_MOUNTAIN and EVENTTRIGGER_HOLY_MOUNTAIN_DONE. The tag to set them to be global or not is "bGlobal". You'll find that it is 0 for the event trigger that starts each quest (except one) and 1 for the "_DONE" event trigger that gives the reward.
