The worst adventure (For my criteria) I found here was not a bad adventure. Just not my type, difficult to put in my campaign or without some of the traits I like more. I found it like an standard adventure (Not like you all don't enjoy them). I read it and I said "Okay, next"
The best adventure (For my criteria) I found here was dificult to read because I was so enthusiast for it that I start to read too much fast and had to stop and reread some parts. I wanted to see the finish and at the same time I didn't want it to end. I took my planning for my next D&D campaing and though how could i put the adventure there, and also share details with other directors and writters.
Between my favourite features was the CW for every adventure and the way they took monsters whom usually are unnecessary portrait as wicked and turn them into victims, heroes or friends. Also, my favourite adventures step away from the usuall "Go to point A, kill something, go to point B, kill something, go to point C, kill boss". They show ways to pass encounters without combat or killing, they reward the interaction and not the murderhobbing way.
Given that the others adventures were between this "worst" and this "best", I could say this is the best anthology of adventures I have, but It may soon lost this title because I also bought the second volume and is my next book to read.
