This package is SO useful. The fact that all of the pins can be added automatically to the actual module maps in Fantasy Grounds is worth the price alone. The maps provided by the author are large, clear and easy to read. The amount of work it must have required to put in individual information for every location in Waterdeep based on all of the D&D content ever published for it is mind boggling. One particularly enjoyable aspect is that I can keep adding pins to the player's version of the Dragon Heist maps and share the info on the pin with the players with each new building they discover. It gives them a sense of place and direction in the city and helps it to feel like a real city and not a fuzzy mental exercise.
If you're running Dragon Heist and you want to really make Waterdeep come alive, it's more than worth the cost.
