How do I play pc games online?

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, through online delivery services such as Direct2Drive and Steam. PC games often require specialised hardware in the user's computer in order to play, such as a graphics processing unit or a modem for online play, although these system requirements are extremely variable from game to game.
