I don't have a lot of experience with Ravenloft outside of reading the Domains of Dread core book from 3E. I just assumed it was meant to be actual gothic horror.That’s just a type of story. You can use the setting without railroading the players through a gothic novel pastiche. A Bulldog Drummond pastiche works just as well. The main difference is the attitude of the players in any case.
In any case, isn't Ravenloft still just medieval-ish?
