My interests as a tabletop designer are mostly narrow, idiosyncratic games that are pretty far afield from D&D: for example, two of my current efforts include "comedic one-shot MegaMan party game" and "contemporary paranormal wilderness survival game". …but I do occasionally wonder how I'd try to tackle designing a standard fantasy fighting-monsters game.
This thought comes because my brother's been running D&D for one of the first times and when he asks for advice I keep having to tell him, "Oh, yes, this isn't a problem for other tabletop games, but unfortunately, you're playing D&D."
