I told myself that I was gonna wait till it went down since it has been out for a couple of months. I went to GameStop and a new copy was still $60 while a used was like $50-$55. I continued shopping and found a new copy at Target 50% off.
Overall I enjoyed the game, but wished it could've been a bit longer. I decided to do the no-kill, no-one-sees-you, no-powers style and I did good and am on the last mission, which I probably finish up today w/ only a little help from the guide (really just the first 3 missions to get the feel of it).
