We’re planning on adding achievements to all of our games you touched on in your mail. 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.
I still haven’t earned all the achievements the game shipped with, and now Valve is heaping more achievements on top of their game, and for my favorite class, no less. Great, as if I didn’t already spend enough time playing Team Fortress 2. The icing on this cake is no lie.
