Valve introduced "Play Next" as an experimental feature as part of Steam Labs earlier this year for testing. The feature previously known as "Experiment 008: Play Next" uses machine learning algorithms to provide suggestions to gamers with extensive libraries on what unplayed or very low playtime game in their library they should try next. This technology is also used in Valve's Interactive Recommender and works by identifying comparable games on Steam. The feature is now live for all users in the latest Steam client update and can be found under the Play Next shelf in library view.
