I would imagine that only new purchases count towards the potato-themed auxiliary power, but the current CPUs is some combination of unique launches and length of play.
This way they can market the potato sack while encouraging playing of game by both old and new purchases alike. That would tend to make sense since these games have been updated/tweaked in various ways as part of the lead up to Portal 2
Otherwise, I would guess-timate that the needed totals vary from game to game based upon prior sales numbers. Regardless of the reason, it is obviously that X number of current CPUs varies from one game to another, at least as a matter of percentage of completion.
Meanwhile, with regards to unlocking the game early, it looks like this would not happen prior to Sunday night, if not more likely sometime on Monday. I am hoping they will reduce the requirements, else it is not much of an early unlocking and misses the big, open period of the weekend.Even more of a letdown since the countdown was to a countdown.
Not sure what I would have done Friday night...but just waiting on Amazon now,
Everything is awesome!!!http://www.kindafunny.com/I love you, mom.
