IMPORTANT

This mod also includes changes for the original civilizations. However, because of limitations of how artdefines work, the new styles are mixed with the old ones. If you want to prevent this, just download these files to replace your base game files (In most cases its like "...\SteamLibrary\steamapps\common\Sid Meier's Civilization VI\", you can also "Browse Local Files" with your steam client).

There are two variations, one with a custom increased city sprawling and one with Vanilla's city sprawl (choose the latter if you are having CPU issues):

Increased Sprawl: https://we.tl/t-1wldeMHp57
Vanilla Sprawl: https://we.tl/t-VZ9aape1se

REPLACING THESE FILES MANUALLY IS REQUIRED FOR THE MOD TO DISPLAY ALL CITYSTYLES PROPERLY ON VANILLA CIVS

PLEASE NOTE: It's highly suggested to make a backup of your files before replacing them with anything.

City-Styles assigned to official Civilizations and City-States

If you want to check what Civs have what style, and also to check what Canals, Monuments and Palaces are applied to each style you can do so by looking at the following doc reference:
Leugis Civ VI City Style Cultures Guide[docs.google.com]

Aside from this, the Scottish, America, Baltic and Brazil city-styles receive their own Monument art. All ancient city styles added support the Cahokia Mounds improvement art. The replacement files also increase the Sprawling from cities slightly.
