The campaign is not perfect and as written is a bit heavy-handed in its direction, but I suspected that this would not be a problem in play and so it proved. All the necessary information is there, but laid out in an expected order that I knew wouldn't match up with how any group of players would approach it; a bit of creative reshuffling was in order, but it all worked out in the end.
The characters are for the most part not an active group, consisting of Ben's psychologist, the painter who helps him with his dream studies, as played by Manoj, and Ric's decadent Oxford don. Only Stuart's globe-trotting American author -- some bloke called Ernest Hemingway -- seems to be of much use in a more physical confrontation. The first session -- apart from the small matter of a riot breaking out at the theatre, in which Hemingway defended the meek don from a maniac wielding a broken bottle -- was less physical than cerebral, so the group's weaknesses in the latter area have not yet been exposed.
As of the end of the first session, the group had access to one Mythos tome, the professor was plagued by disturbing dreams, the painter had gone temporarily insane after reading the aforementioned tome, and the psychologist was worried about everyone's sanity. Hemingway just wanted a drink.
