This is an interesting little article about the 7 things that D&D can teach you about storytelling. Even outside of just being a storyteller, the list is very useful for understanding what makes a good game or character.
1: Characters are more interesting when they’re flawed.
Like most D&D nerds, I cheated when I started playing. I fudged rolls. I had a character with three stats at 18 (the maximum), which I later calculated had a roughly 1 in 40,000 chance of happening without the aforementioned cheating. When I bought a character generator for my computer, though, I “accidentally” made a character named Crystal.
Crystal was in most ways an unexceptional person: a bit charming and graceful in her way, but frail, less than bright, and lacking in common sense. Rather than following any traditional path, Crystal was a fighter wielding a quarterstaff—a fundamental tactical mistake, especially given that this was back in the days of 2nd-edition D&D (THAC0 for the win).
I loved playing that character. Part of it was the challenge, part of it was a protective feeling for my own frail character, but the major draw was something more significant. I came to realize: The best heroic journey is not the story of an incredible person doing incredible things. It is the story of a flawed, ordinary person who—when called upon—rises to an incredible challenge and finds within themselves something truly extraordinary.
