And why would anyone want to pre-order a game anyway? At worst it only sells out for two weeks from the release date. Maximum. Sigh...you kids today...
What is this "sell out" of which you speak? Are you referring to some arcane method of distributing software as encoded dots on plastic? Dude, last century called.... they want their outdated distribution model back. :D
I kid, I kid! But seriously, I do kinda laugh at the concept of buying software on physical media any more. I haven't bought a single game from a shop in nearly 7 years. And I live in NZ, internet is not that flash here!
