- Valve, creators of best-selling game franchises (such as Counter-Strike, Dota 2, Half-Life, Left 4 Dead, Portal, and Team Fortress) and leading technologies (such as Steam and Source), today launched user-defined "Tagging" of products on Steam, a leading platform for games and software with over 75 million accounts worldwide.Now available in beta, Tagging gives Steam customers the ability to "Tag" any title with genres, themes, attributes, or any other term or phrase. The most popular tags on any given product will be surfaced on said product's Steam page and allow users to easily find other products associated with that same tag.As with the " Recently Updated " section launched last week, Tagging is designed to provide more ways to discover interesting content on Steam.Additionally, a related product section was launched today, making it easy to browse by any of the frequently used tags assigned by the community."As the catalog of products available on Steam continues to grow, we want to ensure that it is easy for customers to find the particular types of games or software they are looking for," says Al Farnsworth of Valve. "With this new feature, we are providing another powerful tool to help organize and browse products on Steam."User-defined Tagging is available in beta form immediately and is accessible to all Steam users.For more information, please visit http://store.steampowered.com/tag
