I’m running my first module campaign ever after being in DnD since my teens. The idea used to seem so foreign to me, but trying it I find that it works well as inspiration. I end up adding a lot and chopping out huge pieces and doing substitutions.

Honestly, I think that’s all modules are good for. Maybe older ones were higher quality, but the one I’m using is mostly fluff and vagaries. Suits me fine though, I know how to tune an encounter, but I’ve burnt through a lot of my major campaign plots already. As this one goes and characters get more involved I may discard the thing altogether.
