I'm far from the best DM in the world, and one of my major flaws is the inability to think beyond a few familiar adventure plot tropes and goals. With that in mind; I come to you, ENWorld, for advice. What I want is an exhaustive list of adventure goals and/or plot tropes from which I can imagine new adventures without resorting to the same-old-same-old. I would also like to know of any interesting twists and combinations you can list for me.
Here are the goals I can think of:
Adventure Goals
Kill specific monster/group of monsters
Kill BBEG
Stop BBEG's plans, without necessarily killing him
Retrieve item(s)
Retrieve person(s)
Deliver item(s) within a time limit
Escort person(s) (without them getting killed)
I know there are more, but I cannot think of them
HELP!
