Steam’s had a problem with “fake games” since opening the floodgates on their store, with loads of low-effort titles hitting the service with promises of free Achievements and easy access to trading cards. Valve’s made changes in the past designed to combat that those titles, and now the company has announced even more measures to address the issue.
Valve keeps an internal confidence metric on unknown titles, and that metric will now apply to both achievements and the game’s contribution to your Steam game library count. Games which haven’t reached the appropriate confidence rating will be limited to 100 achievements, won’t contribute to your overall achievement count, and won’t add to the displayed number of games you own on Steam.

“As you can guess,” Valve says in a private Steamworks post, “fake games were inflating achievement and game counts for users to display on their profiles. Our data shows that an insignificant number of users were taking advantage of this, but the existence of these fake games still confuses our algorithms and users.”
On games which haven’t yet met the required confidence, a message labeled “Steam is learning about this game” will now appear in the features list of that title’s store page. (Here’s a current example of a game still pending approval.) When moused over, that message lays out all the restrictions detailed above.
