SimCity 4 contains 6 pre-made regions, two of which have pre-made cities. There were no major bug fixes as part of this release. It is a release of both SimCity 4 and the Rush Hour expansion bundled together with numerous particle effects added and fixed. The Deluxe Edition was released in September 2003. Rush Hour also adds some European inspired buildings and U-Drive-It mode. This expansion adds several things, mostly transportation related, such as elevated rail, ground highways, and toll booths. Rush Hour is an expansion for SimCity 4 released in September 2003. If the Rush Hour expansion is installed, players can also access the U-Drive-It Mode from here. My Sim mode lets the player create or import a Sim from The Sims and place them into their city to get feedback. They can unlock extra reward buildings by fulfilling special requirements. Players have the power to add zones, roads, and ploppable buildings in this mode. In mayor mode, the player's goal is to construct a city while keeping their budget stable. Mayor mode is the main focus of the game. God mode is unavailable once the player has established their city, except with the help of cheats.

Players can also perform operations that alter the entire tile, such as erosion. God mode offers advanced terraforming tools, as well as brushes for trees and wild animals. In God mode, the player can modify the terrain with near complete freedom, unlike mayor mode. The player can adjust each buildings' individual funding and each building also has a maintenance cost. Rather than affecting the town citywide, civic buildings affect only a nearby area. The player now has several modes to use, each mode serving its purpose in creating and handling cities.Ĭivic buildings were also altered. Since the player can populate the entire region and is able to rely on other cities, small towns become a viable possibility. Not only does the player get to negotiate deals with neighboring cities, but the player is also able to build the neighboring cities. The biggest change was the addition of a regional gameplay. As with previous installments, much of the previous game's gameplay was retained in SimCity 4.
