Actually... while you're correct that part 3 had to have a fairly large rewrite and edit due to the author writing an adventure and a half's worth of words... Part six did not have that problem. It is not truncated. What you see is what there was, for the most part. If there are errors or parts that don't make sense, it's because of an error during development where I wasn't as clear about something, but there wasn't much at all left on the cutting room floor after we were done with "Spiers of Xin-Shalast."
Thanks for the reply James. I really love all the work on RotRL, just to let you know that. When I read part 6, I just got similar vibes as in part 3, where some things seemed cut down. The example of the wendigo allegedly being before the dwarven cabin and the paragraph discussing how we could learn about Karzoug's backstory and how to defeat him in Xin Shalst. My assumption had been those things were loose threads hanging from a larger manuscript that had been honed down.
It really means a lot to me that the good folks from Paizo are on here so frequently and reply to our concerns and comments so rapidly. I know you've heard this a million times by now, but it can't hurt for me to lop so praise on you as well. I'm 3 sessions into RotRL and my players are having a great time. It's definitely a refreshing turn of events after the last campaign we were all in - inexperienced DM at the reigns without the desire to put much effort into creating a homebrew campaign, though he refused to use published modules to help himself out. Now that I am back at the helm, people are loving the chance to experience everything Pathfinder has to offer.
