I absolutely loved this module. I ran it at my local game store, and everyone had a great time. It did unfortunately run very long, almost six hours, but that was really just because there was so much content I wanted to include.
I particularly loved the amount of freedom it left for a DM. I took the opportunity to go hog wild with the full suite of monsters between the vanilla Monster Manual and Mordenkainen to have them fighting dinosaurs, devils, a t-rex, and aberrations. I had my players in the gambling hall actually play blackjack with playing cards I had brought. All of the NPCs were interesting and well fleshed out, and I felt like I had everything I needed to roleplay them well. It really felt like the people were real, they all had their own things going on and were doing things even while the party wasn't around them. The mysteries were engaging, the few players who were taking notes were constantly talking through what was going on and throwing theories out. Everything was foreshadowed well, and they figured everything out right when they were supposed to. I really thought that they'd get stuck on the puzzle with the moon door, but exactly one of my players had a eureka moment right when he saw it, and the whole table thought he was a genius.
My players only had three combats, and they were all challenging without being impossible - nobody in the party died or even went down at any point, but they all thought there was no way they would defeat the final boss, after it opened up with a Chain Lightning and nobody passed their save it really looked hopeless, but they used the portals creatively and were able to win, partially because I thought it would be really fun when the boss was surrounded that they casted Shatter targetting themself to burn the whole party, but they all passed their saves and the boss didn't (woops) and I should've just dimension doored out.
In terms of production, this was by far the best-presented adventure I've ever run in AL, and that's including the DDAL adventures. The other ones often railroad the players pretty hard and leave out important information so the DM has to make something up on the spot - not to mention grammar errors and ambiguous language. This was free of all of that. I always had the information I needed right where I expected to find it, and I didn't notice a single typo.
There was clearly a lot of love put into this adventure, and I heartily recommend it, either for AL or a casual game. The best AL adventure I've ever played.
