Civilization VI December 2020 Update

The December 2020 Update for Civilization VI was released on December 17th, 2020.
==New features==
===City-State Picker===
In Advanced Setup, players can now bring up a new menu to choose which City-States they would like to include in their next game. Selected City-States are not guaranteed to be in the next game, rather, they are part of the pool of City-States that will then be randomly selected and placed. Ones that are not selected will never appear in a game.
===Searchable Unit List===
Leave no scout, archer, or Giant Death Robot behind. Players can use search and filtering functions in the World Tracker panel to quickly find any unit on the map.
