The Steam Workshop is a central hub of Player-generated content from select Steam platform games, providing tools to publish, organize, and download. Different games utilize the Workshop in different ways. Some games, like Team Fortress 2, allow the player to create and submit new items (such as hats, weapons, badges, boots, and more) for consideration to be incorporated into the actual game. Other games like Elder Scrolls V: Skyrim allow mod authors to publish their work directly to the Workshop, and let players subscribe to mods they want to use in their game.
Steam Workshop launched on February 2, 2012 with support for Elder Scrolls V. Less than two weeks later, it was reported that more than 2 million mods had been downloaded and from a selection of more than 2,500 mods uploaded by users.
