One of the advantages of digital distribution is that you'll never run into a sold out sign - or so we thought. Steam seems to have completely run out of 2K's Prey. Who knew?
2K's futuristic alien shooter Prey was part of the ongoing Steam end-of-the-year sale, until they ran out. That's right, Steam is completely sold out of a downloadable title, running out of keys for the game before the sale could run its course. How does this happen? Well this is speculation, but I would assume a game like Prey requires some sort of CD key, which are generated by the company selling it on Steam, and there is a finite number of them available.
That, or they were stolen by key gnomes. Goddamned key gnomes.
It isn't a total loss, however. 2K has replaced Prey in the sale with 75% off of BioShock. $4.99 BioShock trumps Prey at any price.
