Ah, sorry, should have read your first post more closely.
Does it really not say that anywhere? I'll have to check my Beginners' Guide to see if it's clear on the subject...
[It's funny how, when we know things so well, we sometimes forget what it was like to know nothing. When I'm hired to analyze how a co. does things and prepare their ISO application or training manual they are surprised with all the things they don't think about but are critical to how things work.]
I stumbled across it after my first frustrating game when my cursor accidentally rolled over a grayed-out Specialist and caused the info pop-up to...pop-up. I don't see very well but made out the red lettering that states, "Requires Market or Grocer" (for the merchant specialist).
Before posting questions on the CF Forum I search the War Academy for articles and the threads with key words. I've skimmed nearly every War Academy article and thread haven't found it specifically stated.
And not only does no one mention it but in "[A] Guide to City Specialization and Land Improvements" by Excl, it specifically states,
"The sole purpose of the GP Farm is to generate a ton of Great Person points. One way to do that is to build wonders. But the other, easier way to do it is to have a ton of specialists. You can do that by having an extreme abundance of food."
A few paragraphs later:
"The City Buildings you build are only going to be the ones you need to boost happiness and healthiness. No need for banks or barracks or the like here."
Correct banks and barracks don't allow one to create Specialists but "or the like" needs some clarification and expansion.
I understand this is the "Quick Answers" thread but if I may be allowed to offer the following text for anyone's use in helping others:
"The following explains what is needed to create Great People (GP):
The 1)
Currency tech, to build a 2)
Market city improvement, to allocate up to 3)
two 4)
merchant specialists, who generate three Great People Points (GPP) each, and serve as a source for generating a Great 5)
Merchant.
Now, insert the following, corresponding numbered responses (1, 2, 3, 4, 5) from any single line below.
Merchants:
1) Currency; 2) Market; 3) two; 4) merchants; 5) Merchant
1) Guilds; 2) Grocer; 3) two; 4) merchants; 5) Merchant
Scientists:
1) Writing; 2) Library; 3) two; 4) scientists; 5) Scientist
1) Astronomy; 2) Observatory; 3) one; 4) scientist; 5) Scientist
Artists:
1) Drama; 2) Theater; 3) two; 4) artists; 5) Artist
Prophets:
1) Priesthood; 2) Temple; 3) one; 4) priest; 5) Prophet
1) Music; 2) Cathedral; 3) two; 4) priests; 5) Prophet
Engineers:
1) Metal Casting; 2) Forge; 3) one; 4) engineer; 5) Engineer"
Then I would post a link to that article that talks about the % odds of generating a GP of each type based on # of sources and not the # of GPP each source contributed. Also see sections on Wonders and Civics.
Back to "Quick Answers". I apologize for the conversation.
