I cancelled my Amazon pre order, and went to a 24 hour Wal Mart at midnight to pick it up. The game is amazing. The only complaint I can muster is the facial graphics on NPC's are not very good, but everything else is top notch. I also got one of the best Achievements ever on total accident.
Spoiler:
Its called "balls" In an alley in Detroit there is a basketball hoop, and a ball on the ground. I was goofing around with it and starting shooting the ball into the hoop. It was hard at first, but eventually I figured it out and moved way back, let it fly and nothing but net. Then I got the 'balls' achievement. Hilarious. I was determined to make that damn basket, and was rewarded for my efforts haha.
