You know my collection. I've only added to it over the years since. Some of the adventures need characters introduced beforehand, in order to (try to) build up any necessary relationships the module might require or swapping out the victim of the module with an already established ally (Target: Hero).
Some adventures need their seeds sown, in game time, before you start running (Shades of Black comes to mind).
Very few modules were actually one-off, pick up and start running. Which is why I'll borrow ideas and whatnot, but run with the game world as is.
