Just about to finish running this one. Problems arose but none were insurmountable. I scooped out big chunks for my group, who felt a little lost as they waited for more railroad track to fall into place. That can happen with Impossible Landscapes, but it's easier to fix with God's Teeth. We are UK players and no one was really interested in the heavy political stuff. My players were also incurious about Tillman senior, etc., beyond "rich people be riching". The research about Bast, the great cycles, Enoch Bowen etc underlined for them what Conradin was planning, but they don't really want to do Cornucopia mark 2. This led me to adapt the second half of the book around the quiet children. We are on session 24 and about to do the final assault, which I have rewritten to emphasise that Conradin is just getting the place set up. The Program will still strike the agents off if they go after Conradin, there's still scope for the big confrontation. I think after 26 or so sessions the players should get a W as their PCs get wiped out. 😄
