Nurturing a small town to life and watching it grow into a bustling metropolis is just one of the many appeals of the SimCity experience. But before you start paving roads, plopping utilities, and laying out zones, it’s a good idea to establish a basic understanding of the game’s terminology. Here’s a quick rundown of some common terms you’ll come across during your career as an esteemed mayor.

Approval Rating: This communicates how happy your Sims are with how you’re running the city.

Building: Formerly ploppable, this describes anything you can place (or “plop”), which includes buildings, modules, and things like Water Towers. It does not include zones, roads, or things that are painted onto the terrain.

Challenge: This is a general term for the weekly/global challenges offered by the game.

City Site: This is a selectable area of a region in which a player can choose to build a city, before a city is built. Once a city site is claimed, it is simply referred to as a city.
