What was/is your favorite Call of Call of Cthulhu Adventure?

[Cearlan]

Has to be Masks of Nyarlathotep for me. As has been mentioned the first chapter of Shadows of Yog-Sothoth - the Hermetic Order of the SIlver Twilight and The Pale God from the Great Old Ones were stand-outs as well. There are just so many, so much quality!

I read somewhere - YSDC I think - of a bastardisation of some of the main campaigns. Basically whoever it was, was running Masks with addons. In came Silver Twilight which turned out to be a(nother) front for NWI, Jeremy in the well, Castle Dark, Mountains of the Moon and several other mainstays. Hell of a lot of work for the keeper, but what a great game to play in.

The reason I like the "Masks" so much would be the Egyptian chapter.  "Under the Pyramids" is one of my favorite H.P.Lovecraft stories, and when I found the rpg, that was the story I wanted to emulate for my first game.

 "Masks" has got to my favorite with Horror on the Orient Express a close second.  You're they do take a long time but losing your Sanity goes a long way to keep the adventure fun.

as for me I managed to scare my players with short adventure from the rulebook - the one about watler corbitt haunting the house;
apart from that I had lots of fun with terryfing adventures expansion;
unfortunately my players dropped the hobby before we managed to play masks of nyarlathotep
