I can only imagine how many times this question has been asked before. It seems like a biggie. I apologize in advance if I missed some big thread on this topic.
When GMing, do you prefer to use premade adventures, or make your own stuff up? Or, what combination of both do you use (if applicable)?
I, personally, have always made my own stuff up from scratch. I never even fathomed getting a module or adventure path until I went on here and saw how many GMs did just that.
