I just got this game for my birthday yesterday and played it with my wife and another couple. It was really hard! But we still had tons of fun. We missed one really important rule: advance the doom track for every investigator devoured. We were basically losing 1-2 investigators every round and had only one left in the investigator stack when Cthulhu finally awakened. Miraculously, we were able to defeat the Ancient One.
I hear a lot of people say this game is easy, but it was downright brutal for us. We started off with three Midnight effects: two of them dealt damage and one added a monster. Combined with Cthulhu's ability to decrease maximum stamina and sanity, we lost investigators very quickly. Do you think it was our setup, or do we just need to play more?
I can't wait to play again!
