I have only run a group through the first narrative, but we very much enjoyed it. The descriptions and atmosphere were evocative, a key in any Cthulhu game. My only real complaint is one that is typical of modules with pregen characters, and not a major issue at that. Assumptions are made, and advice is given, for what the player characters might do. A necessary evil, I realize. My players, of course, did nothing of the sort. They camped out over night at the train wreck until help arrived, and only when it did not did they actually go on in to Dover. They avoided anything of interest in town to make it to the Inn. It was only in the final scene that they attempted anything out of the ordinary, something that was frustrated by the continuing earthquakes. My players ran their characters as ordinary people (who may have seen a little too much Jeeves and Wooster) and not Investigators. As I said, all enjoyed the game, but in retrospect I think I should have made a little more preparation to adapt to my players and perhaps adjusted their expectations a little as well.
