I stopped my first play though at the pit and restarted because pt1 is additional content and I am the type of person who doesn't like to do multiple playthroughs without a lot of time in between. So as I am trying to decide whether to purchase pt2 at the same time as pt1 I realized I know nothing about pt2 and would not want it if it like pt1 adds nothing to the main story line. Thanks in advance for any info.
