I really enjoy SS&SS and I look forward to the proposed scenario book!
Meanwhile, I'm thinking of using the campaign system from 5 Leagues from the Borderland to generate a campaign for SS&SS. A system for generating random campaigns for solo SS&SS would be good, too!
I've also considered using 4AD, CCC, FotW, or Man-Eater! to generate indoor and outdoor adventures for SS&SS. A Ganesha fantasy mash-up?
