Civ VI: How Do City Borders Expand?

[OphidianX]

Searched forums and the in-game documentation.

I'm having difficulty figuring out:

- How can you tell when a city is going to expand? (i.e. like in Civ5, the accumulation of culture toward border expansion is clearly illustrated.)

- Is there a way to identify which tile the city is going to expand to?

Thoughts, anyone?

Pretty sure its still culture but there is no information in the game to let you know this or show you where it will expand next.

Best guess is it is still similar to 5 and will grab resources and flat land tiles near the city first before grabbing rougher terrain, deserts etc.

There is no information provided in game.... however, the XML files indicate that

1. tiles are obtained with culture produced by the city
2. the culture cost of a tile is 10+6*n^1.3 (where n is the number of tiles obtained by culture already...not sure if gold bought ones count)

 

[zimniejszy]

correct formula is 10+(6*n)^1,3

 

[KrikkitTwo]

So basically

correct formula is 10+(6*n)^1,3

10+10*(n^1.3)

Do the XML files reveal the formula for choosing which tile to obtain next?

 

[zimniejszy]

So basically


10+10*(n^1.3)

no

 

[KrikkitTwo]

no

Well 10.270619.... technically (thats 6^1.3)
Which means approximately
10+(6*n)^1.3~= 10+10*(n^1.3)
[assuming you are certain that is how it uses the XML]

 

[zimniejszy]

10+(6*0)^1,3=10
10+(6*1)^1,3=20,27
10+(6*2)^1,3=35,29
etc.
those r values that r required for next hexes

Ok good to know (simple version is 10,20,30...but with the 1.3 pushing it slightly farther....

So getting a total of n tiles
~10n+4.5*n^2.3
~11,000 for all 3 rings

 

[zimniejszy]

yes, or ~5400 if playing as Russia
