Forum poster "slugz" (not his real name) says he received the following note from Valve staffer Erik Johnson in response to a fan letter: "We're planning on adding achievements to all of our games you touched on in your mail [Half-Life 2, Half-Life 2: Episode 1, Day of Defeat: Source and Counter-Strike: Source]. We're just now coming out of the post-shipping haze, so these should start showing up on Steam pretty quick here. We're also planning on adding a bunch more to TF2, starting with an achievement pack for the Medic in the next week or so." Another poster says they got a similar email later in the thread. We've emailed Valve for verification, but it certainly seems plausible enough. What achievements would you like to see in those Valve games?
