Cities XL 2011 is the sequel to the city building/managing simulator Cities XL and as such, it expands on the gameplay of the first game.
Among the new features there is a subway system, a basic sandbox mode has been included, there are now five different roads textures to choose from (default, US, German, English and French) and 300 new buildings have been added to the previous list. Another novelty is that different cities of the same planet can be connected now to trade between them. Additionally, 2011 includes three new maps (Hollywood, Hong Kong and Krakatoa) and three new content packs (medieval, Chinatown buildings and US buildings). The sequel, however, will not count with a multiplayer mode this time, as Cities XL did.
Like the previous Cities XL game, the player can build their cites using three types of zones: residential, commercial and industry. The residential areas are designed for four different social classes that range from unskilled workers to elite and there are five different types of industry that require different types of workers and conditions (transportation, surrounding zones, etc.), which accounts for most of the problems the player has to deal with as the major of their cities.
