Green Cities Update

Lore & Background

The game's engine was designed to simulate nearly a million unique citizens navigating daily routines, making the visual indication of traffic congestion an easy-to-comprehend sign of larger design problems. In this simulated world, road systems form node-based graphs determining fastest paths for commuters who do not swerve unless rerouted. The Green Cities mechanics integrate into this system by allowing players to configure districts with specific regulations focused on environmental impact, such as banning all private cars or encouraging the adoption of electric vehicles to drastically reduce CO2 emissions. The expansion reflects the developers' intent to present complex simulation data simply, allowing players to easily understand problems in their city's design through specific policy interventions.

In Their Own Story

A player designated a new district near a major freeway, aiming to reduce noise pollution affecting nearby residential zones. Using the Green Cities features, they applied a regulation discouraging fossil-fuel vehicles from entering while allowing electric ones. Immediately, the traffic simulation adjusted; electric trams and buses began circulating freely, reducing the density of polluting cars. The player observed that noise levels dropped as vehicles adhered to these new district constraints. This change allowed property values in the surrounding area to stabilize, countering the negative effects of highway proximity. The decision mirrored the broader game goal where visual traffic flow serves as a diagnostic tool for city health. By restricting vehicle types, the player effectively managed the balance between industrial access and residential comfort, demonstrating how specific district rules can alter the daily routines of simulated citizens.

Reader's Guide

To implement Green Cities mechanics, players must first designate parts of their city as districts. Within these bounds, specific regulations can be enforced to manage development types or traffic flow. One key feature allows the player to discourage fossil-fuel vehicles from entering a district while not discouraging electric ones. This is particularly useful for reducing noise pollution caused by traffic in residential areas. Another option involves offering free public transportation within the district to reduce overall traffic volume. Players can also restrict industrial sectors to agriculture only, or adjust tax rates for various development classes. These tools require careful planning of road systems and zoning, as the game's node-based graph determines how citizens navigate these constraints. The goal is to balance economic needs with environmental factors like noise and air quality.

Did You Know?

• The Green Cities DLC allows players to ban all private cars or encourage the use of electric vehicles in a district, but does not support banning only fossil-fuel vehicles while permitting electric ones.
• Districts can be configured to offer Free Public Transportation, though this policy was originally introduced in the Base Game, not by the Green Cities expansion.
• While specialized agriculture zones allow for farming-only industrial sectors, this specific zoning capability was introduced in the Natural Resources DLC, not Green Cities.
• The primary impact of banning private cars or encouraging electric vehicles in Green Cities is the reduction of Air Pollution (CO2), rather than Noise Pollution.
• The game engine simulates nearly a million unique citizens whose daily routines are affected by these new district policies.
