Post Description

With Cities XL 2011, build and develop gigantic cities on realistic 3D maps,
  thanks to an incredible collection counting more than 700 buildings and
  unique structures. You are the virtual mayor and as such, you will need to
  find the right balance between economic development for your city, public
  transportation, housing, social services, leisure activities and even special
  events in town. Realism has been pushed a little bit deeper with larger
  cities, more realistic and more sophisticated than ever before!Widen your
  horizon!Cities XL 2011 pushes its limits further: hundreds of new buildings
  and structures appear for a total of more than 700 constructions, leading the
  way for new building and combinations options never seen before in a City
  Builder. Many new maps are also available, for a total of 45 buildable maps.
  City management will offer the full experience thanks to the addition of
  public transportation (subway, bus) which will decongest downtown traffic
  while lowering pollution levels and increasing the population's satisfaction.
  A more elaborated tax system will let all apprentice mayors adjust personal
  and local business taxes. A new commercial user interface will permit trade
  between cities in single player mode if a player decides to develop several
  cities. Thanks to these big novelties and to a lot of inspired improvements,
  Cities XL 2011 truly reaches a whole new dimension to please all City
  Builders fans!
