Civilization VI will have an focus centered around the map itself. Land Tiles are much more important than in previous version of the game.
“In previous Civilization games you had Workers, which took their time going around the map, taking a number of turns to make each improvement. Automation was a way for players to get a benefit out of their Workers without manually controlling them each turn, which was often difficult because you would forget what it was you had planned when it came time for your Worker to move on to a new project.”
Replacing workers with builders is a bold step for Civilization. The game mentality will completely change for players as alot more though will have to go into how your build your cities.
