Explain to me, please, about adjacency

[MinnesotaRuss]

Please explain what "adjacency" is and what it means. If two districts are next to each other, is there more produced? (i.e, more culture if theatre?)

Every district in the game has certain conditions that give it a raw bonus. This is almost always caused by the tiles surrounding the tile where the district will be placed. Each district has different adjacency bonuses. As an example, a holy site district gets +2 faith for being next to a natural wonder and +1 for being next to a mountain. So, if you placed a holy site on a tile that had 5 mountains next to it, it would get +5 faith. If you had a holy site next to two tiles that were natural wonders, you'd get +4 faith (2+2).

Adjacency bonuses are always collected whether a citizen works the tile or not. Placing a district completely destroys all normal yields, so placing a district on a +3 food tile means the tile can no longer be worked for that 3 food. Because of this, it's often advisable to place districts on bad tiles such as ice, tundra, and desert and never on tiles with high yields, like a marsh/rice tile.

In general, most districts get a 1/2 point bonus from being next to another district. So, if you put a theater square district next to the city center (which counts as a district) and an encampment district, it would get +1 culture from being next to two districts. Half point bonuses are rounded DOWN. Meaning you get nothing from being next to a single district and only +1 from being next to 3 districts.

The notable exception to the 1/2 point bonus is Japan -- they get a full +1 bonus. Also, the encampment, entertainment, aerodrome, and space port districts are not associated with any yields, so they don't have any adjacency bonuses; however, districts placed next to them do get their bonus (as in the example above with the encampment and city center). The city center does have a raw yield, but it can not be improved with adjacency bonuses.

Off the top of my head, these are the adjacency bonuses for each district:

City center: None
Holy site: +2 natural wonders, +1 mountains, +1/2 woods/jungles/other districts
Campuses: +1 mountains, +1/2 woods/jungles/other districts
Encampment: None
Commercial district: +2 from a river (not stackable ie - only +2), +2 from a harbor, +1/2 from other districts.
Theater squares: +1 world wonders, +1/2 other districts
Entertainment districts: None
Harbors: +1 from sea resources, +1/2 other districts
Industrial districts: +1 from mines/quarries, +1/2 other districts.
Aerodrome: None
Spaceport: None

Such a clear and excellent answer. I've always ignored those policies that give +100 percent adajency bonus. Bus, I see they are very important. Is there a best way to use them? Because we get so few slots

 

[joncnunn]

Also Australian appeal bonuses appear to be counted as "adjacency bonuses" for the purposes of civics that give bonuses to adjacency bonuses in the current patch.

 

[ShakaKhan]

Also note that improvements have adjacency bonuses, and some of these are only activated by certain technologies.

Nuke, I thought Holy Site only received +1/2 from Woods (And mountains/other districts) and Campus was only Jungle (And mountains/other districts). Not both as your post suggests? Was this updated recently?

Some minor mistakes:

Holy Site only gives +1/2 for woods, not jungles.
Campus only gives +1/2 for jungles, not woods.
And clarification: bonus from other districts and 1/2 bonuses are counted seperately, so having 1 district plus 1 woods won't give your holy site an additional faith.

Something to consider is that it would appear that city-state boosts to districts are counted as adjacency bonuses for most (all?) relevant effects.

 

[MadDjinn]

the CS bonus yields aren't considered 'adjacency bonuses'. They are added into the same tooltip info though, which makes it more confusing.

 

[Magil]

the CS bonus yields aren't considered 'adjacency bonuses'. They are added into the same tooltip info though, which makes it more confusing.

Consider the wording of the Madrasa: "Provides bonus Faith equal to the Science adjacency bonus of the district". My experience with this building--and modded buildings that use the same effect--is that it considers the bonuses provided by city-states as part of the "adjacency bonus of the district".

I'm not sure (and don't think) it applies to policy cards, which is why I only said "most", though I know Land Down Under seems to be doubled by adjacency-related policy cards. But now I'm going to need to go test the policy cards in Firetuner to see what they do and don't affect, I guess.

 

[MadDjinn]

Land Down Under provides adjacency via appeal, so it should be affected by the card. CS bonuses, not so much.

wrt the Madrasa, that's probably a bug.

 

[Magil]

I thought it was relevant for Hildegard, but a quick test shows it wasn't. I'll still say it's rather confusing sometimes, as the Madrasa does use the bonus provided by city-states to determine its Faith output, even though it says "adjacency", while the text for Land Down Under doesn't mention adjacency in its description yet is doubled by policy cards.

Side-effect of working with modded buildings that use that particular bit of code, I suppose, that made me think it was more widespread than it actually is (in the base game I think only the Madrasa and the Shipyard use it).

 

[MadDjinn]

Land Down Under mentions the 'yields from' which is basically the adjacency bonus related ones. It makes sense that it is an adjacency bonus one because it's asking you to move away from the standard adj/ bonus sites and drop into high appeal sites instead.

 

[Magil]

If that is the intent, I'm not sure how successful it is in execution, as many of the features that those particular districts get adjacency bonuses from also grant appeal to adjacent tiles, including: woods, mountains, rivers, World Wonders, and Natural Wonders (going by this list). Seems like more often than not it's going to be at least a slight buff to placing it where you were going to put it anyway. On the other hand, it does discourage you from dropping mines and quarries (along with certain other districts) next to those districts.

 

[MadDjinn]

yup. but it also means that Appeal boosting items are more appealing... (insert pause) as it will eventually also boost yields on districts.

 

[ShinigamiKenji]

Compiling some info about civ-specific adjacency bonuses:

• Australia: Commercial Hubs, Campi, Holy Sites and Theatre Squares get +2/+4 bonuses from being placed in Charming/Breathtaking tiles, respectively. Though not "adjacency bonuses" per se, they are counted as one.
• Brazil: Commercial Hubs, Campi, Holy Sites and Theatre Squares get +1 bonus from every adjacent Rainforest. Neighborhoods get +1 housing for every adjacent Rainforest as well.
• Germany: The Hansa (replacement district for Industrial Zone) get +2 adjacency bonus for every bonus, luxury and strategic resource. It also gets +2 bonus from an adjacent Commercial Hub.
• Greece: The Acropolis (replacement district for Theatre Square) get +2 bonus from an adjacent City Centre. It also gets a +1 bonus for each adjacent dstrict instead of only 0.5 bonus
• Japan: All districts get a +1 adjacency bonus from each adjacent district instead of only 0.5 bonus.
• Norway: Stave Churches (Temple replacement) adds an additional +1 bonus from adjacent woods to the usual Holy Site bonus.
• Poland: Holy Sites get +1 adjacency bonus from each adjacent district instead of only +0.5 bonus

It's also useful to know that the pantheons Dance of the Aurora, Desert Folklore and Sacred Path also count as adjacency bonuses from their respective terrains.

 

[Magil]

• Greece: The Acropolis (replacement district for Theatre Square) get +2 bonus from an adjacent City Centre.

It's worth noting the Acropolis also gets +1 from each adjacent district (instead of +1 per two).

Thanks, fixed that.

 

[sa1vy]

Do aquaducts (and baths) and neighborhoods (and Mbanzas) count toward to +1/2 adjacency for neighboring districts?
I hardly use any of those (well, sometimes Mbanzas and baths)... but I'm curious.

Yes. Or, well, I'm certain of Baths, which are actually quite useful: +4 housing +1 amenity.
