Preordering only gets bigger because people are becoming idiots
wow, deep analysis from you there.. ok, I guess people are "idiots" for buying a game they have waited for for years.. sure.
as I stated; logic is simple, here is how it works:
A) go to the store on release day and buy a box - get the full game
B) buy it months ahead, get the full game + get access to cool stuff you only get in pre-order.
That's it. Trying to brand people that does it unintelligent is quite useless, subjective and immature, and really doesn't make any difference to anyone else than yourself.
About the "brainwashing" remark. My answer is: "wow, teh interwebz must really have swung the conspiracy theory hammer on you, hasn't it there?"
