I don't think I have ever used a published module exactly as written (except maybe very early in my GM career). Sometimes the changes are necessary, sometimes I adjust it to fit better with my group and sometimes they simply add to the fun.
Realizing that it's a basic game tutorial, most changes will probably be minor - but what additions, tweaks or adjustments have you made to Escape from Mos Shuuta? How did they turn out for you? Would you do the same thing again? What would you recommend for other GMs just about to run the game?
