Out of curiosity, can you recommend any #ttrpg / #dnd "checklists" for

- designing campaign settings
- designing campaigns
- designing adventures?

I mean, I know how to do all those things if I am running games. But it might be a useful exercise to fill out such checklists for that setting based on German #folklore that I keep daydreaming about - this way, I could figure out which elements are already covered by folk tales and which I need to develop on my own.
