A personal computer game (also known as a computer game or simply PC game) is a video game played on a personal computer, rather than on a video game console or arcade machine. Computer games have evolved from the simple graphics and gameplay of early titles like Spacewar!, to a wide range of more visually advanced titles.

PC games are created by one or more game developers, often in conjunction with other specialists (such as game artists) and either published independently or through a third party publisher. They may then be distributed on physical media such as DVDs and CDs, as Internet-downloadable shareware, or through online delivery services such as Direct2Drive and Steam. PC games often require specialized hardware in the user's computer in order to play, such as a specific generation of graphics processing unit or an Internet connection for online play, although these system requirements vary from game to game.

Computer games and game addiction are often the subject of criticism, focusing largely on the influence of objectionable content and prolonged gameplay on minors. The Entertainment Software Association and other groups maintain that parents are responsible for moderating their children's behaviour, although the controversy has prompted attempts to control the sale of certain games in the United States.
