Valve Corp. has notified developers that some games available over the Steam marketplace will now be restricted to 100 achievements, and that feature will be subject to other constraints, as part of efforts to thwart “fake games” on the platform.

It’s probably not going to affect many, or even any, games most players are familiar with — Valve said “an insignificant number of users were taking advantage” of inflated achievements and game counts. But it’s a step the company has taken to police content in its marketplace, even after a week after it formalized a broadly permissive content policy that many (including us) criticized as an abdication of responsibility.
