I am currently playing through this module with a group of experienced players and an experienced gm. Our gm doesn't like to pull punches and likes to have the group figure things out. 6 session in and I still don't really know where we should be going. We are undergeared and under level for many of the encounters we have run in to. We have experienced several character deaths because of this which has ruined the experience for me because I can no longer take the story seriously. The gm is also pulling punches which also spoils the game for me because I feel no accomplishment.
The characters who perished were investigative types who are being replaced more combat optimized characters. Yet another blow to the mood of a lovecraftian horror game.
I hope this book is just a hiccup because the first book was really amazing.
