What changed with industrial zone placement?

[Artifex1]

I took a break and am now returning to the game. I played a couple months back when you spammed them in every city, wasn't there a nerf and now just build in capital?

 

[Eagle Pursuit]

The nerf is that when a city is within range of multiple industrial zones, only the one with the strongest effect will affect that city to the exclusion of others. I am not sure if that includes the city's own industrial zone or adds on top of it.

It works the same for the entertainment complex as well.

The restriction applies as well to any Factory in a city's IZ, even if there is another Factory within 6-tile range -- as you say, the Factory with the highest bonus is the only Factory that applies.

For example, if you have 3 cities that have an IZ with a Factory and all 3 IZs are within 6 tiles of each of the 3 city centers, each city would, under the pre-patch rules, get to stack 3 Factory bonuses. But the patch eliminated stacking of regional bonuses, so post-patch each city can only get 1 Factory bonus, whether or not it has built it's own Factory. However, the Factory bonus that will apply is the Factory with the highest yield. So, bulbing the Modern Era Great Engineer Nikola Tesla in the IZ for City C would boost City C's Factory by +2 production, and the enhanced Factory bonus from City C would apply to all three cities (in lieu of the bonuses from City A and City B's existing Factories, which do not enjoy the Tesla boost).

So build IZ in every 3rd city more or less?

 

[Browd]

Not necessarily. There's no need to build a Factory (or Power Plant -- same rules apply) in every city, but IZs and Workshops are unique to the city in which they are built -- they have no regional effects. So, using my 3 city example, if you build an IZ only in City C, only City C gets production from that IZ -- Cities A and B get no benefit from City C's IZ. Same goes for a Workshop built in City C -- the workshop bonus in City C applies only to City C. Yes, when you build a Factory in City C, its effects will extend to Cities A and B, in addition to City C, but is that all the production you need in Cities A and B? Perhaps so, in which case you can choose to build different districts, or no districts at all, in Cities A and B -- it's your choice, your game.

I find I tend to plan for one IZ for every 3-4 cities to get factory coverage for each city, but often times one of the other cities will still put an industrial zone down, if you can get at least a +2 adjacency, or if you have 1+ industrial city states that you've put envoys in. But yeah, it just means that those extra guys will probably not build a factory at all, although occasionally if I run out of other things to build, I might still build the factory to essentially give me a backup in case if an enemy spy kills the IZ in my capital.

Workshops still give their bonus in addition to the IZ itself; also, GPPs if getting GEs are important to you.

That being said, IZs aren't 100% essential anymore. I find that foregoing them in cities that have a factory bonus can be just fine. I'm not sure on the actual math but foregoing the IZ+workshop and just building other districts and buildings probably saves more cogs anyways. If it doesn't then it's gotta be pretty close (making the IZ+workshop mostly unnecessary anyways).

 

[PlotinusRedux]

6 envoys in every industrial CS + CS of same faith give 50% bonus can make an IZ in most cities worthwhile (+6 for every IZ per CS of your religion), even if you don't build anything in it.

I captured 3 Russian cities and after making peace noticed that an IZ was within 6 tiles of all 3 cities. However on checking it out only one city showed the IZ. I thought all 3 should show possession of the IZ?
I find this issue confusing. how do I know if the other 2 cities are getting the IZ benefits?

 

[Leyrann]

You just count tiles. The IZ is owned by one city, but the Factory and Power Plant bonuses also extend to the other cities.

 

[CPWimmer]

The IZ (and the buildings) still only belong to one city. The bonus for the Factory and Power Plant (if the IZ has those) are what spread to the other cities. If you select one of those other cities, and hover your cursor over the Production amount that is shown (the number next to the radio button you can select to have the city focus on production) it will give you a tool tip that tells you how that number is calculated. You should see a +3 bonus labeled "Factory".

 

[jbxx]

Many thanks. It wasn't clear to me and I didn't realize it was just factories and power plants that spread their wings!

 

[Cymsdale]

Think of things like factories and power plants as having a coverage map, and cities either fall under coverage or they don't. It'd be awesome if there was a map mode to help with this.

*gasp* Wait! You mean like a useful lens?

Hey, Settler lens are useful for spotting City-States and rival Civs! Granted, they might be the only useful one...

 

[VicRatlhead5199]

Would love lenses for IZ and ED coverage.

I hated this change at first but now I'm starting to like it. I'm still spamming CHs everywhere but I found districts I only rarely used before the nerf are more useful now, like the harbor and encampment. The change actually helped add a little more welcome variety to my cities and the great people I earn.

Yeah, before it used to be all about "how can I max my IZ coverage", but now it's a lot better being "how can I make sure that every city is covered".

I kind of wish that every district had regional buildings. If every district's final 2 buildings had regional effects only, I wonder how much more strategic the game would be, then.

 

[KmDubya]

Before I would really work out where to place Industrial Zones to get the most overlap for my bigger cities. Now I look to build them in the optimal location, as far as proximity bonuses, regardless of whether or not it has coverage to other cities. I still build them in every city just like Commercial Districts, maybe I waste a few factories that are not optimal but it works fine for me..

Now Entertainment Districts I try and site where they can cover the maximum number of cities. Since they do not get any proximity bonuses their placement is much more flexible.

The More Lenses mod has a 6-tile radius and a 9-tile radius lens.

Ooh! Getting that one. So tired of counting tiles.
