In discussing my Iron DM "Home Game" entry, I realized I'm not a fan of modules with extensive background. As I said there:
Do you feel that more background detail is always better?
I'd like to hear how other people feel about background, because I think of it as the kind of thing that often reads well but doesn't play well. I like a backstory that's coherent and just complex enough, not one with dozens of twists and reversals before the party even shows up. (If anyone has Aldriv's Revenge, the KoK module, it's wonderful, but the backstory is entirely too convoluted and detailed, at least for my taste.)
