There is a couple of very interesting classic modules (TSR, and also Hungarian modules for our D&D equivalent MAGUS) which i would like to run, but I dont want to use their original trad system because... you know. I'm not talking about open sandboxes á lá Judge Guildes, I'm talking about The Sinister Secret of Saltmarsh or Queen of Spiders for example.
1. Theoretically speaking, is it possible to run their content with a Story Game system without breaking one or the other? If yes, how would you do that? What are the possible dangers and pitfalls?
2. Also a subquestion about railroadish modules. Do you know any game which help you to run them? Which can give the players fun but help you to elegantly maintain the prewritten plotline? There is an infamous MAGUS module for extremely high level characters. The story is very grandiose and plotted. I've always wanted to give it a try but never know how.
