Zones in New York
Cities are divided into different geographic areas, or zones, as we refer to them in The Great Heist. The local politicians determine how each zone is developed and maintained. Travel between zones can be costly, so plan your movements with care.
Regarding Zone Quality
The quality of a zone affects the businesses and locales in it, the people living there, and the visitors passing through.
The quality of a zone is mainly determined by the quality of its locales and its infrastructure. It's up to the local politicians to make sure the infrastructure is maintained properly. Other factors such as crime, pollution, and overcrowding can also affect life in the zone in some way or another.
