Shortly after Valve updated Steam with a Recently Updated feature, another change has come to the digital store.
Steam Tags is a new system whereby users can help categorise games by applying tags that they feel suit the titles in question. As more and more tags appear over time, the community's feedback will be used to better define titles in the database, hopefully improving the discoverability of different games when making specific searches.
We'll be able to browse Tags that have been recommended to us personally, or just sift through the more popular options. New filtering will give users better tools when looking through the extensive back-catalogue of games on Steam, hopefully helping us to unearth a few hidden gems along the way. More details here if you want them.
