Oh, everyone who's played it and knows me just kind of gapes when I say it's my favorite, because most people just find it too creepy! But it plays differently than a lot of RPGs-- or at least it does when Jason runs it, I've never played with anyone else gamemastering-- since most games tend to be hack-and-slash, all about killing monsters. In Cthulhu, as Jason always describes it, "You hope you DON'T MEET the monsters." But this means there's more focus on OTHER kinds of skills than just fighting, like RESEARCH and stuff! It's actually an awesome game for librarian-characters! Also, Jason likes to set his games in the 1930s and involve Nazis, so it gets very Indiana Jones.
