I keep thinking "I bet if I did the work to figure out a game's rules and built stuff around it I'd be a pretty good tabletop DM"...

and then I remember I'd basically roll dice behind a screen for show, completely ignore the result, and go with whatever I think would be the better story so it wouldn't even be a game as much as collaborative roleplay where a fey mischievous deity keeps tugging puppet-strings for its own amusement.
