I loved how it expanded Chapter 1 and the extra details for the faction missions they cover (Zhents, Gray Hands). I wish they had continued with expanding the other factions but I feel like I've got enough of a template now to do it myself. The Chapter 2 supplement had some really great interactions with Trollskull Alley NPCs. My players particularly loved Avi and Ember's expanded interactions. I highly recommend for helping to get the campaign off the ground and giving ideas about how to embellish the campaign. I haven't used the later chapter supplements yet.
