I would LOVE to give this collection a 5 star rating, as the content that is included here is very well done. The expanded faction missions for Grey Hands and Zentarim are amazing as I really felt Chapter 2 in the Dragon Heist book was severely lacking in details and it felt rushed. The maps are very helpful especially if you play on a VTT like Roll20, or like me use a television to display maps.
Sadly, I feel the collection falls short in some key areas. Despite the promise that "all future Dragon Heist updates will be included" it seems that there is no plans to add any more to this collection, including expanded quest details for the other factions (Lords Alliance, Harpers, Emerald Enclave, Force Grey, Order of the Gauntlet, and Bregan D’aerthe). This was probably the most frustrating for me personally.
The same thing can be said for Chapters 6, 7, and 8. They are all just missing. And again, this collection falls short on the heisting lairs supplements. It includes some awesome content for Heisting Xanathar's Lair, but nothing is provided for any of the other villian's lairs. So unless you are choosing Xanathar (Spring) as your villian, then you will be missing out on quite a bit of content.
With this missing content included, this collection would be 100% worth the high sticker price of $14.95 and a 5 star rating. I feel this collection was priced and written with the intent to complete it. Unfortuately, it seems the authors have abandoned this collection to work on Avernus.
[4 of 5 Stars!]
