I've always felt that the Curse of the Dark Pharoah was judged too harshly by most players. It's probably my favorite small box expansion, and perhaps the single best addition to Arkham it conains are the three Dual Color gate cards, each of which allows a single player to encounter and fight an Ancient One in a specific other world.
For a long time I've let those cards gather dust in the box with the rest of the CotDP expansion (Though I like CotDp, I have my hands full with just Dunwich and Kingsport, plus the Dunwich dilution factor which would come into play if I added CotDP), but a few days ago I decided to add just those three cards to our current set-up. Tonight one of my players was Devoured by Ithaqua:)
Don't get me wrong, I would have been pleased as punch if the player had beaten Ithaqua, but having him Devoured was almost as good! Just encountering Ithaqua in that manner added greatly to the game, in my opinion. I would encourage any player who enjoys challeng and doom to keep those three cards in their Other World deck, and I wonder: With Innsmouth only adding sixteen gate cards, is there any real chance that a few of them will be dual color?
