Nearly all global PC game sales now come from digital distribution services. Physical retailers now only sell game cards and codes that can be used on platforms like Steam, Origin, and GamersGate. Some of these services even allow you to download old MS-DOS games.

Below are some of the best PC game download platforms currently available.

Steam is a digital PC game distribution service, social network, and gaming platform developed by Valve Corporation. It was unveiled in 2002 and officially released in 2003. Since then, it has become the de facto leader in PC gaming, with a service for purchasing and downloading games as well as a thriving user community and gaming platform hosting millions of users on various games at any given time.

Steam hosts thousands of titles, including most major releases, with the exception of a few EA titles that are exclusive to EA's full platform, Origin. Valve has also developed games that are exclusive to Steam, such as Dota 2, the Left 4 Dead series, and Counter-Strike.
