Since its launch in 2011, the user-generated Steam Workshop has now paid out more than $57 million to those creating various in-game items for Team Fortress 2, Dota 2 and Counter-Strike: Global Offensive. And now Valve is expanding the list of supported games, meaning even more money-making opportunities for Steam users.

According to the news release more than 1,500 contributors spread out across 75 countries had created over 100,000 items in the Steam Workshop across the three games, an astonishing rate for any user-generated content machine. While such profits have been limited to Valve games, the digital store owner has announced that two non-Valve games will be making their way to the curated store: Trendy Entertainment's Dungeon Defenders: Eternity and Torn Banner Studios' Chivalry: Medieval Warfare.

This is really exciting news and means that more high quality content will be available for the game you love playing. Plus, purchases of this great new content directly enables those community members to continue practicing their craft and making more awesome content.

We expect more curated Workshops to become available for creators and players in various games over the coming weeks and months.

Of course Steam Workshop supported games have been around for awhile now, but this new addition of curated, paid-for titles will definitely favour more revenue opportunities. And Valve isn't stopping there, with more games expected in the coming weeks and months, so keep your eyes peeled for the news.
