Ok... So look at it as "It release on October the 12th for people buying it day one". Problem solved.
If you weren't going to buy it day 1, then why do you care if I play it earlier than you?
That you're getting to play the game isn't even part of the equation in my case.
The game is getting delayed for me, because im not willing to blindly pre-order it.
Just pretending this isn't the case doesn't make this issue go away, as you imply in your first paragraph.
The game is being withhold from a subset of customers to give the subset of preordering customers completely artifical, actually worthless "value".
The people who preorder don't get fuckin' anything, they get to play the game on the date it would've been released regardless, but the people that don't preorder are getting punished.
