I LOVE Arkham Horror with a burning passion, and when I found out that FF made an expansion based on my favorite H.P. Lovecraft story, I almost had a seizure of happiness. This big box expansion comes with more mythos and other world cards, as well as a set of Innsmouth Look cards which have killed me and my friends more than once. It also comes with aquatic movement monsters , more investigators and the the town of Innsmouth add on board. It can be challenging at times but then again, it is Arkham Horror. I recommend this to any fan of Lovecraft and the Arkham Horror series.
