Just from what I've heard (I'm not a proponent of this BTW) it pushes games and locks them into a release date they might end up needing more time to develop, end up releasing a buggy POS. They box it up with preorder bonuses and in game items that are exclusive to the pre order/CE that, some say, should have been available in the game to begin with but is now a "purchase" item (see Cash Shop threads). It encourages lazy developing. and i'm sure if you googled "Preorders are ruining games" you could find more details straight from the horses mouth so to speak.

I am for preordering games cause of the place I live. If i don't preorder, I will probably never see it, unless its COD, Assasins creed, or Halo. I just remembered seeing all this outrage about it then I come here and there is opposite outrage. I see the pros' and the con's, just wanted to throw this out there.
