Simcity 4 carries the traditions of Simcity franchise and adds quite a bit more content. Simcity 4 adds a region play feature. In Simcity 4 your city will be affected by adjacent cities that you create. You can also trade resources. It's still possible to build a self-sustaining city. The main game mechanics of Simcity like RCI demand are enhanced. It's a lot harder to make a New York-like metropolis without putting in any effort. Commercial and residential buildings are grouped into stages and wealth levels. From the Stage 1 low capacity buildings to the tall Stage 8 skyscrapers. Wealth levels range between § symbols to §§§ symbols. Industrial buildings range from farms, to dirty and high-tech factories. Education, pollution, police and fire coverage and healthcare still work hand in hand. City ordinances are always around, helping you improve city conditions with simple enactments. What sets Simcity 4 apart from every other Simcity: User made content. Simcity 4 has by far the largest variety of custom-made content. I direct you to Simtropolis, the largest repository of Simcity content on the web. 7500 FREE fan made buildings ranging from landmarks to fan-imagined creations to bus, train and subway stations, to trees, to beaches and forests to bridges, etc. And that is still increasing in number. You have every tool and resource to create any city that you want. There are city journals to highlight that point.
