Valve has also loosened its control over sales data. Creators now have explicit permission to share their sales info with others "as they see fit," whether it's with other companies or the public. While there have certainly been other ways to find out whether or not a game is a hit, this could eliminate some of the guesswork.

The new agreement also includes some basic GDPR compliance info and has required some basic safety warranties for VR games. Studios have to ensure that a VR title won't cause physical harm, and that they won't override SteamVR safety features like Chaperone (which keeps you aware of the real-world play space boundaries).

The revenue changes won't please indie game makers for whom the usual 70 percent revenue isn't always enough. However, it might increase the chances that publishers and developers will stick with Steam instead of launching their own services and cutting Valve out of the loop.
