Whether this was an accident or planned operation- I feel horrible for the guys and girls who've gotten Black Ops II and ended up with a Mass Effect 2 CD. I mean, my girlfriend and I waited in line for 7 hours yesterday being on chairs with blankets over our cold bodies just to get the game. If I came home to pop the disc in only for it to be ME2 (which I already have) .. oh, boy. I... I would be upset.
So Bioware, or Treyarch .. whatever happened, I feel it's only going to bring you guys a lot of heat. Nothing to gain from this.
