for each game they intend to publish. Once they apply, a developer must wait thirty days before publishing the game as to give Valve the ability to review the game to make sure it is "configured correctly, matches the description provided on the store page, and doesn't contain malicious content". On announcing its plans for Steam Direct, Valve suggested the fee would be in the range of $100–5,000, meant to encourage earnest software submissions to the service and weed out poor quality games that are treated as shovelware, improving the discovery pipeline to Steam's customers. Smaller developers raised concerns about the Direct fee harming them, and excluding potentially good indie games from reaching the Steam store. Valve opted to set the Direct fee at $100 after reviewing concerns from the community, recognizing the need to keep this at a low amount for small developers, and outlining plans to improve their discovery algorithms and inject more human involvement to help these. Valve then refunds the fee should the game exceed $1,000 in sales. In the process of transitioning from Greenlight to Direct, Valve mass-approved most of the 3,400 remaining games that were still in Greenlight, though the company noted that not all of these were at a state to be published. Valve anticipated that the volume of new games added to the service would further increase with Direct in place. Some groups, such as publisher Raw Fury and crowd funding/investment site Fig, have offered to pay the Direct fee for indie developers who can not afford it. Games discovery changes Without more direct interaction on the curation process, allowing hundreds more games on the service, Valve had looked to find methods to allow players to find games they would be more likely to buy based on previous purchase patterns. The September 2014 "Discovery Update" added tools that would allow existing Steam users to be curators for game recommendations, and sorting functions that presented more popular games and recommended games specific to the user, as to allow more games to be introduced on Steam without the need of Steam Greenlight, while providing some means to highlight user-recommended games. This Discovery update was considered successful by Valve, as they reported in March 2015 in seeing increased use of the Steam Storefront and an increase in 18% of sales by revenue from just prior to the update. A second Discovery update was released November
