Prerequisites for Best Events/Quests

[Fistleaf]

Most of the time, we will stick to our preferred playing styles and use only our favorite civics and build preferred buildings/improvements. However, events and quests will only occur for certain civic/building/improvement combinations.

Which are the combinations that are prerequisites for the best events/quests to happen? With this knowledge, this will encourage the change of one's playing style in terms of civics, etc just to have a chance of getting the good events to occur. If we keep sticking to our own preferred civics, for example, we may never ever get some of the great events happening even after playing hundreds of games of Civ4.

[Lancer]

Can anyone outside the game designers have this info? I never thought about it but yeah I'd love to know the answers too. This is a really good one Fistleaf.

[DaveV]

Try this thread on CivFanatics. It gives all the details about each event and quest.

[Fistleaf]

That thread includes all the events, but I'm only interested in maximizing the chances for the good events. Perhaps somebody has already done up a summary of the prerequistes required?

[Theben]

If you read thru the thread you can figure out your self what you need to maximize your chances for good events. It'll change thruout the game as other civics/techs become available so unless you wish to build 9 chariots/swordmen/triremes, etc. ahead of time I'd stick with your basic plan and not plan around events.

[Fistleaf]

I won't plan around events, but it will be good to know when I am only 1 chariot (your example) short of triggering an event. It is not too hard to build 1 more chariot.

Just had that quest, apprently you can trigure the quest for Chariots without a single one. On a normal size map, you need 8 to fullflll the conditions of the quest. And you must not reach the classical era before it. ***

*** However, it appears that you can get extended time if you bypass the classical era entirely by researching Theology which is a Midevil tech.

However even in this case the first Classical era tech will expire it even though your Midevil.

Of note though, I think this inadvertly opened another strategic decision. Before it was thought your only options when going after this tech was when a Chariot rush was already planned or else wait until you can afford to dedicate a city to Chariot burning and then turning research off as soon as the last ancient era tech was reserached until the quest was completed. Now though, you can devote your science beakers to Theology.

Incidently in this same game almost immedately after failing the Chariot quest (I didn't even start it because opponents were outside Chariot rush range and also I had made the decision to go for the Oracle) it gave me the Triembre quest. I did happen to have a city that could afford to build 7 of them in a row.

In retrospect though both of these quest offerings would have been much more useful in AU 302 Holiday Surprize than the current map.

There are other beneficial events not included here that can be triggered if resource tiles are improved (e.g. mine and road on a coal resource).

On a related note, the dreaded slave revolt will only occur if city pop is 4 or more.

[Fistleaf]

Of particular note,

1. Build libraries in every city to trigger event 106.
2. Build at least some walls and castles to trigger some events.
3. Very beneficial to trigger Event 64.
4. Build and keep 1 airship if you have Airports.

[jkp1187]

Note that not all of these events will trigger in every game. So while it's good to try to keep some of the prerequisites for these events filled, it does not guarantee that doing so will trigger the event for your civ.

[Fistleaf]

There are quite a number of events here that will be included 80% of the time or more. So the chance of an event occurring is still rather high.
