Steam Workshop
CONCEPT
A website where you can submit, find, rate, and download new content and modifications for some Steam games.


First appearing for Team Fortress 2, the workshop was used to allow customers to vote and approve of user-made hats and items that Valve might opt to include in the game. Since then, the scope of Steam workshop has expanded to include mods, levels/maps, and other features as new games are added. On October 2, 2012, GameMaker was added to steam as along with other non-gaming software, increasing the scope again to include player-created games.
