Traditional explanatory page here, but I guess this is Valve's solution to the discover-ability problem. Slightly depressing that they nicked the idea from Kongregate, but still.
You can tag games or software in the Steam Store with terms that you think are appropriate, or apply tags that others have already suggested for that title.
Apply genres such as Puzzle, themes like Military, or attributes such as Difficult. Or, come up with entirely new concepts to apply in categorizing products.
Browse a new section of the Steam Store to discover games and software, organized by the most frequently used tags.
Plus, narrow your search to just products tagged with the terms you and your friends have applied.
Browse by tags recommended based on the games you have played and software you have used recently.
As you browse for products by tag, youll find new filtering controls to help narrow your search. Now you can easily find those single-player, platformer games, that run on Linux and have Steam Achievements, Steam Trading Cards, and Full Controller Support.
Q. What if I don't agree with a tag that has become popular for my game?
A. Tags can be a good indicator of when there is a mismatch between how you perceive your game, and how your game is perceived by customers. Often this is simply because there is some piece of information regarding the game that customers feel is missing from the store page.
