You’re going to see a more personalised list of Steam recommendations now, as Valve has rolled out some changes to the algorithm which will more heavily prefer games you might actually like, instead of just the titles that are more popular. You should be seeing these changes take effect everywhere Steam recommends games as of today – just ahead of the new Steam library beta.

Valve’s vague about exactly how these changes work – likely in an effort to prevent exploits of the system – but one of the changes is an expansion of the time period used to calculate popularity, which previously created “unpredictable visibility for some games.” There are some bug fixes in all this, including a bug where the ‘similar by tags’ was getting more heavily influenced by top-rated games than intended.

The new system already rolled out to around 5% of Steam users over “the past few weeks.” Users in the experimental group were 15% more likely to click on recommended games.That drove an overall 75% increase in unique games visited, and a 47% increase in unique visits per game – all of which suggests this is broadly positive for both players and developers.
