Seriously, Day 1 DLC for $10 is like a $10 tax on stupid people.
Indeed, stupid or the impatient.
I've been burned soooo many times, rushing out to buy games on day 1, only to be greeted with a pile of digital bovine residue. This DLC bull is just another way to be disappointed, if anything this additional $10 price gouge is encouraging me to wait until the game is re-relased in the GOTY edition, typically with all DLC included at half the price.
So for me, this is the last straw. The pain at the cash register is starting to far out weight my enthusiasm to purchase on day 1, and with the many scars of bad games past that I'm bearing... I think I'm just going to wait and get it cheaper later. If anything... thank god for Gamefly!
