$57 million US is a lot of money. So’s $58 million, but I mention $57m specifically because that’s how much Valve have paid out since 2011 to folks who made and sold in-game items for their games. It’s over $57 million dollars from hats, knives, guns, staves, and swords across TF2, Dota 2, and Counter-Strike: Global Offensive. And those last two games only sell cosmetic items. And that’s after Valve have taken their cut. Crumbs!
Now non-Valve games can join in. The first games opening up a ‘curated’ Steam Workshop bringing items to sale are Chivalry: Medieval Warfare and Dungeon Defenders Eternity.
