So, my nefarious scheme worked! My group is going to play Call of Cthulhu by Chaosium. I downloaded and checked out the quick start rules, and it seems like a great system. I won't be running the game, which is another bonus!
However, none of us have ever played CoC before, and I have, by far, the most experience with horror games (running them). The guy who is going to be the Keeper has no experience with CoC, either.
So here's my question: other than "The Haunting" adventure contained in the quick start rules, what would be the best adventure to try to get our hands on for a group of brand new players to CoC, and a brand new Keeper? We don't want to run that one because most of us have read through it already to get an idea of what the game is like and how it differs from D&D, which is our staple game. Or, if there really isn't an adventure out there that suits those needs other than "The Haunting", let me know that, too.
