is a city-building and urban planning simulation massively multiplayer online game developed by Maxis, a subsidiary of Electronic Arts. Released for Microsoft Windows in early March 2013, it is the first major installment in the SimCity series since the release of SimCity 4 a decade prior. An OS X version was released on August 29, 2013.
The game is considered to be a reboot of the SimCity series. Players can create a settlement that can grow into a city by zoning land for residential, commercial, or industrial development, as well as building and maintaining public services, transport and utilities. SimCity uses a new engine called GlassBox, allowing for more detailed simulation than previous games. Throughout its development, SimCity received critical acclaim for its new engine and reimagined gameplay; however, publications cautioned the game's use of a persistent Internet connection, with which it stores saved games and allows players to share resources.
Prior to release, SimCity received positive reviews; however, the game's launch was met with negative reception as a result of widespread technical and gameplay problems related to the mandatory use of a network connection to play and save game data. These issues included network outages, problems with saving progress and difficulty connecting to the game's servers. As a result, some reviewers were unable to review the game, labeling the launch a "disaster" and the game as "unplayably broken", urging players to avoid purchasing the game until the issues were resolved.
