Another Himedere checking in. I love setting up situations where the players and/or the characters squirm in anguish about what to do.
My favorite so far was an estranged princess living as a man and hostel owner. He had turned his back on the throne and wanted little to do with it. As a bonus he was the only child of the king's only remaining child. Fast forward a bit and he needed a (legal) favor from the king. Went to court and met with his grandfather. The king would do it, no strings attached if a) he returned to court and resumed his duties as prince and b) sired an heir.
There were a good thirty minutes of the players anguishing if he should accept while going deep into character motivations and the setting. During that game I don't think I did as much concrete worldbuildning as during those thirty minutes. I loved it, the players loved it. Great time.
The chosen one trope hands down all the time. I would love to get through Wheel of Time but I cannot stand chosen

Rand and everyone around him is
That series I have put down so many times. Having a "hero" protagonist that is essentially unkillable (because they are the title character) I don't mind, Conan for example. We all know Conan won't die because there is always another story about him. But he is not fated for anything, no grand destiny he has to achieve or the cosmos suffers.
Second is also another that has been touched upon - the goodness of divine authority. Especially if it is light flavored. And nobles divine right to rule set as a standard of good etc. Give me stories of folks fecking up the system and creating their own anarchistic communities while continuing to feck up the system.
