"Shadow Over Innsmouth" is one of my favorite H.P. Lovecraft stories, and this expansion was a must-have for me. Extra monsters are always nice to add. The extra characters are also great, 16 this expansion!. The 96 personal story cards adds to the base game a lot of characterisation for the investigators. More Ancient Ones - 8 with this expansion! - are also very cool. The board also neat; I imagine the smell of rotting wood beside the sea every time I look at it. This is a neat expansion, I prefer it over Kingsport.
