Stardock Corporation is a software development company founded in 1991 and incorporated in 1993 as Stardock Systems. Stardock initially developed for the OS/2 platform, but was forced to switch to Windows due to the collapse of the OS/2 software market between 1997 and 1998. The company is best known for computer programs that allow a user to modify or extend a graphical user interface as well as personal computer games, particularly strategy games such as Galactic Civilizations, Galactic Civilizations II, Sins of a Solar Empire and Elemental: War of Magic. Game development is handled by the company's internal division Stardock Entertainment, which also works with 3rd party developers to publish games for Windows PC.
Stardock created and maintains WinCustomize, a graphical user interface customization community, and developed the Impulse content delivery system before its sale to GameStop. Many of the skins and themes featured on its site are for software that is part of Object Desktop, their main subscription service. They are based in Plymouth, Michigan, USA.
