City projects

[oPunchDrunko]

How exactly do city projects work?

In my current game I have 4 cities that I do all of production in and about 15 that I dedicate to city projects like campus, commercial hub, encampment, etc.

I really can’t notice a difference when I start or finish a city project, whether it’s science points, more gold after it’s done, etc.

So, how does it work?

 

[Rosty K]

It increases some of your yields while it's running (not when done), and generates GP points when done.

 

[oPunchDrunko]

That’s weird. When I have commercial hub city project going I never noticed an increase of gpt... and this was with about 3-4 of them.

 

[Rosty K]

Never paid attention. This is Civ6 UI though, a lot of things can happen

The GP points appear on the great person screen on the turn the city finishes the project. Where your normal might have been 7, it could become 23 just for this turn, for instance.

Yeah I’m aware of GP points, but that’s not what I’m worried about. Some projects like commercial hub project give you a certain amount of gold as well as GP points. I haven’t really noticed getting a gpt increase from projects like commercial, encampment, etc.

The amount of production for a project it takes is based on district scaling.
This production dictates the outputs
15% of production as science etc... I think gold is doubled
5+production/5 is the GPP

Was curious about this so I checked out the yields details from hovering over the icon and also manually calculated to make sure it was as expected. I did it for campus project though, not commercial hub, but anyway if you hover it should show the yield coming specifically from the project.

Also noted that % modifiers apply after all the 'hard' values are subtotaled and are multiplied always by the subtotal before applying modifiers. For example, my city of Quebec here has a subtotal of 44.1 and two % modifiers. Both of them get multiplied by 44.1 to get their added yields (ie. they don't stack).

Spoiler Quebec yields example :

What I can't figure out though is what determines the yield per turn of the city project. Here my city of Ottawa is also running campus project but with a much lower yeild of 2.6 as opposed to Quebec's 8.1. They both have the same Campus District buildings so that's not it. Anyone know? Sometimes I wonder if I'd get more yield running a city project or producing the next district building and I don't know the answer to that. Intuitively I'd assume that producing the next building and then running projects is better, but what actually determines the project yields?

What Victoria said.

Quebec: 8.1/55.0 = 0.147 = 15% of the production
Ottawa : 2.6/17.6 = 0.147 = 15% of the production

 

[Victoria]

Intuitively I'd assume that producing the next building and then running projects is better,

buildings are long term gain, projects are short term gain of real value only in a high prod city or if you have nothing else of value to your aims or victory condition left to do...or you want that Great person.

I hadn't realised that higher production cities produce more science etc. per turn from a project than lower production cities. Kind of obvious how I think about it, but good to know.

But that would be circular. The 55.0 is obtained after %modifiers are applied including the city project output, so how can the city project output be 15% of a value that's obtained after including city project output? Either that's inaccurate, or my deduction about the way things are calculated is wrong.

Also where is 17.6 from in your Ottawa example, 2.6/17.6 = .147?

The 17.6 is the Production from Ottawa.

It's not circular, she is showing where the number comes from. The 55 is Production, the 8.1 is additional Science generated by the Project.

The yield of the Project is 2.6 in Ottawa. By dividing that by the production you'll find the ratio of project yield compared to the Production. 2.6 (Yield of Project or Campus Research Grants)/17 (Production) = 0.153, or 15.3% which is near enough 15%, which is what she was trying to prove (I get a different figure than her, I think she made a mistake, or I've misunderstood something, but it's the same end result, within reason).

It's just a proof of how the Project yields are calculated, namely, 15% of Production for said city.

Production! Doh! My bad, I thought they were saying 15% of the science yield for some reason and the fact that Quebec has 55 production and 55 Science in this example just fed my confusion. Didnt help that I read the above and replied while half-asleep . Ok that adds up. Thank you for clarifying

Glad I am not the only one that does that
