I've heard about these on podcasts many times, but can't seem to find any information about them. Any idea what differences they bring, and how you go about requesting one?

Press accounts unlock every game on Steam. I have no idea how to request one, but more than likely, they'll be really hard to get. Only people I know that have them are all the big name places.

I seriously need to update my avatar. Look at me, I look like i'm out of a captain birdseye advert. Steam codes are pretty easy to acquire for each individual game, it just requires an additional e-mail.
