I'm sad I'll only have a shot at one potato at most, since I only own Amnesia.
And that game is scary.
I really shouldn't be tempted to drop $40 for...Potato icons.
Also, I'm really impressed with just how elaborate this has all been. I mean, it involves at least 11 other companies besides Valve; the 10 involved in the potato pack and the hardware makers Razer. Content for the ARG has been delivered via email, website, tweet, Facebook, blog, and forum post, and has spanned the whole spectrum of media.
That really seems like a non-trivial amount of effort all to announce...Portal 2 unlocks early? TF2 hats? Portal 2 is being released, period? (I like how it's been the top seller for awhile now)
I really have no previous experience or context to put this in and formulate a reasonable expectation with. Where are we going with this, Valve? And how much is it going to cost me?
