In one of the GURPS Discworld books (and I don’t know if it was the one you two reviewed or the the other one), it talked about humor and the Discworld books, and it pointed out that, while the Discworld books are funny, the characters aren’t themselves, conscious of it. In other words, they’re in situations where they have serious goals (Solve a crime, stop a war, lift a curse, get home, etc) and they’re serious about accomplishing those goals It points out to the GM, if you just put your characters in wacky situations for the sake of comedy without any stakes, it’s generally just bad storytelling, and it sounds like this game suffers from that.
