There are scenarios you play and enjoy; then put into your stack of things to run. My AP group needed an adventure so I prepped this adventure in a hurry. It flowed like water. This is memorable due to the easy to implement favor mechanic between two NPCs and the intrigues of a family. The characters are accessible and as a GM I appreciate having a well thought out paragraph of the character personality that would never appear in a stat block.
The setting and the encounters all contribute to the story and theme. After playing this two weeks before prepping it in a day, I had no problem understanding the encounters, reoccurring NPCs, and keeping the scenario moving.
Role play is great, and everyone else appreciates how itcontributes to the story line. I liked how it was natural and encouraged by the situations in the scenario.
When I have a convention where we play Pathfinder, I keep a printed copy of this and by the end of the event is is the most dogeared mess on my table. That is a pretty good testament, people read it into oblivion in a few days.
I like that it introduces new players to everything about the campaign, short of the entire Pathfinder RPG rule set.
It is hard to write a document that is comprehensible for new players, and still keep is useful for players who played before. I still love the traits. New rules in 2.2 help.
