Great People Tech Prefences

[DaveMcW]

Edit: My original article (at bottom) is obsolete after lots of community research into GP tech preferences. Thanks to notagoodname from the civ4 multiplayer ladder site for putting this new article together.


In the game great people have a list of techs and a preference for each tech (no techs have the same preference). With the same techs researched the same great person type will always give you the same tech.

First: Here's complete list of techs a prophet will get in the order they will try and get them (preference of tech they give you runs from top to bottom)

Great Prophet:
Meditation
Polytheism
Priesthood
Monotheism
Theology
Divine Right
Mysticism
Masonry (Warlords patch & BTS)
Code of Laws
Civil Service
Monarchy
Literature
Music
Writing
Philosophy
Printing Press
Drama
Aesthetics (BTS)
Alphabet
Paper
Education
Liberalism
Calendar
Masonry (Vanilla & unpatched Warlords)
Animal Husbandry
Construction
Future Tech

From that above list you can see that if you dont have meditation a great prophet will give meditation. If you do have meditation a great prophet will try and give you polytheism. If you have meditation and polytheism then the prophet will go down the list (from top to bottom) until there is a tech you can research that the prophet can give you.

Note if you dont have prerequisites for a tech then the great person will try and give you the next tech on the list that you can get.

eg.
If i didnt have masonry and had techs meditation, polytheism, priesthood, mysticism and code of laws then a great prophet would give me civil service as monotheism requires masonry, theology require monotheism, and divine right requires theology.

eg. (from the above list)
Great Prophet:

Meditation // Have it
Polytheism // Have it
Priesthood // Have it
Monotheism // Requires masonry so isnt allowed to be researched
Theology // Requires monotheism
Divine Right // Requires theology
Mysticism // Have it
Masonry (Warlords patch & BTS) // Still playing vanilla Civ4
Code of Laws // Have it
Civil Service // Great prophet will be able to give me this
Monarchy
Literature
Music
etc.

Spoiler Original Article :

I was digging through CIV4TechInfos.xml, and found lots of useful information that isn't in the civilopedia. Here is a compiled table.

Era = there are 6 eras in the game, plus future tech.
Cost = base number of beakers to research the tech. This is modified by game speed (quick 67%, epic 150%), map size (duel 100%, huge 150%) and difficulty level (settler 70%, deity 130%).
Religion = how much a Great Prophet values the tech.
Production = how much a Great Engineer values the tech.
Gold = how much a Great Merchant values the tech.
Science = how much a Great Scientist values the tech.
Culture = how much a Great Artist values the tech.
Military = there are no Great Military Leaders, so I assume this is used by the computer AI.
Growth = same as military.
AITrade = I guess this affects the willingness of the AI to trade the tech?

[Yzman]

I am confused to what it means by how much a prophet values a tech?

 

[DaveMcW]

One of the ways to use a Great Prophet is have him discover a tech. He will pick the available tech with the highest religion value. If there is no religion tech available, he can't discover anything.

 

[snepp]

Handy list, thanks.

Cost = base number of beakers to research the tech. This is modified by game speed (quick 85%, normal 130%, epic 195%) and difficulty level.

This should be quick 67%, normal 100%, and epic 150% (according to gamespeedinfo.xml), unless I'm misunderstanding you.

Also, world size modifies research costs:
100% - Dual
110% - Tiny
120% - Small
130% - Standard
140% - Large
150% - Huge

 

[siff]

Nice one, how did you compile this list from the xml? by hand?

Siff

 

[LeSphinx]

Great Job!!

[DaveMcW]

Thanks snepp, I forgot about world sizes.

 

[Shillen]

When you finish researching a tech there is a popup window with a choice of new techs to research. The game gives two recommendations and puts growth/military/science/culture etc. in parentheses next to it. So I'm guessing that's where the growth and military fields come in to play. I'm sure the AI also bases its research decision on this.

 

[fed1943]

Just a guess,Dave McW:the eight variables are the leader traits.
Can you,please,or somebody else,verify that? (As I know nothing of computers,I'm not able to do it).
Best regards,

 

[BlueRenner]

Dave, just an addendum.

I've dug through the XML too... I came to the conclusion that those values also link back to the "Flavors" of every AI Leader.

Check out the "CIV4LeaderHeadInfos.xml" under the "Civilizations" folder. There are values for "FLAVOR_GROWTH" and "FLAVOR_GOLD", which I took to link back directly to what tech certain AI types favor.

It explains why Catherine, who is heavy "FLAVOR_SCIENCE" goes for Writing so early, yet Caeser, who is "FLAVOR_MILITARY" goes for Iron Working.

- Bill

 

[Pentium]

I suppose it also affects which techs are recommended to you when you get to choose what to research next?

 

[Gyhth]

Religion = how much a Great Prophet values the tech.
Production = how much a Great Engineer values the tech.
Gold = how much a Great Merchant values the tech.
Science = how much a Great Scientist values the tech.
Culture = how much a Great Artist values the tech.
Military = there are no Great Military Leaders, so I assume this is used by the computer AI.
Growth = same as military.

Old topic, but I just found it and just got here, so please forgive my posting late.

What I believe the numbers actually in relation to the Religion, Growth, Military, etc, though it may have to do with the GP ability to research; I wouldn't imagine, say, a priest giving you something like bronze working or another heavily war based tech if they have Monotheism, Meditation, etc to learn - though, if you haven't researched any of them to begin with, I can't really see you having a priest GP - I imagine it deals more towards the AI learning them, but even more so towards the tech list.

When you learn a tech, as most people probably know, beside it, it will sometimes say, "Animal Husbandry (Growth)" or something like that, and I believe that is the primary reason that it's in there; to give people new to the game a guide on what each tech it's self enforces. I imagine it takes into account the cost of the tech, the level of the tech, etc, but I do believe that this would be the main reason it's in there. I can't really see the tech list being able to help people or guide new people if all techs were given the same values in all things.

If I am wrong, I apologuise, but this is what makes the most sense to me. I apologuise for bothering everyone, and I apologuise for posting on such an old topic - I simply believe that this had to be stated.

 

[notagoodname]

/Comes over from the civ4 multiplayer ladder site

That chart isn't really that clear.
In the game great people type have a list of techs and a preference for each tech (no techs have the same preference). With the same techs reasearched the same great person type will always give you the same tech.

Now here's a better way to tell precisely what a great person will give you

First: Here's complete list of techs a prophet will get in the order they will try and get them (preference of tech they give you runs from top to bottom)

Great Prophet:
Meditation
Polytheism
Priesthood
Monotheism
Theology
Divine Right
Mysticism (??)
Code of Laws
Civil Service
Monarchy
Literature
Music
Writing
Philosophy
Printing Press
Drama
Alphabet
Paper
Education
Liberalism
Calendar
Masonry
Animal Husbandry
Construction
Future Tech

From that above list you can see that if you dont have meditation a great prophet will give meditation. If you do have medidation a great prophet will try and give you polytheism. If you have meditation and polytheism then the prophet will go down the list (form top to bottom) until there is a tech you can research that the prophet can give you.

Note if you dont have prerequisites for a tech then the great person will try and give you the next tech on the list that you can get.

eg.
If i didnt have masonary and had techs Meditation,polytheism, priesthood, mysticism and code of laws then a great prophet would give me civil service as monotheism requires masonary, theology require monotheism, and dive right requires theology.

eg. (from the above list)
Great Prophet:

Meditation // Have it
Polytheism // Have it
Priesthood // Have it
Monotheism // Requires masonary so isnt allowed to be researched
Theology // Requires monotheism
Divine Right // Requires divine right
Mysticism (??) // Have it
Code of Laws // Have it
Civil Service // Great prophet will be able to give me this
Monarchy
Literature
Music
etc.




Now if you understood all that here is the full list of what great people will give you (preference runs top to bottom on all)

Great Prophet:

Meditation
Polytheism
Priesthood
Monotheism
Theology
Divine Right

[DaveMcW]

Yeah, that list has been floating around CFC for a while buried in various threads. But rather than burying it in this old article, it might be better to start your own article.

 

[Sir Janus]

Great work everybody- and something else to factor in. I seem to remember that loads of posts were saying Civ4 was a dumbed down version of civ3 - if only.

I can't help feeling that there is something important hidden in those lists (other than the obvious insurance policy against missing the Oracle). Has anybody had time to do some analysis? (Isn't RL a real bind?)

I hope that if/when I beat deity on a reasonably large map (dream on) that I have to use every single tactic (read exploit if you prefer) known to man - and have a lot of luck. Balance wise I think the game designers (and play testers) have done an exceptional job (except for the always anarchy thing).

 

[Codeman]

i'm glad you put the work into this. thanks.

 

[Martinus]

Wow, thank you very much for compiling these lists.

This looks like a potential basis for an awesome multiple-slingshot strategy, especially for Philosophical leaders who can afford a heavy-specialist strategy (I'm thinking of Peter here).

 

[juggerxnaut]

thank u thank u very very much!it s just the right thing i want.
after long being bored with the regular route, it gives me some clues to develop a new tactic.
now im going through a new game with gandhi.awesome,the first prophet sent
me Civilservice,before i rushed the second GP(scientist) by caste system.
with bureacracy and academy ,my tec soaring.
after that i have been devoting to produce prophet(though it might not be the best way form a stratigic point,just for fun and see how the prophet actually works )
exhilaratingly the tec route in a straight and clear way goes forward.paper,education,liberalism,awesome,perfect.
thank dave again,u bring me a new godd playstyle,thank u.

 

[Eqqman]

It also turns out that a GS always contributes at least 500 more beakers to a tech, which will make a difference in your planning at the stage when a single Great Person won't finish the tech completely.
