I haven't found any Twine documentation providing advice on how to choose a story format, but this choice seems awfully important. (For that matter, I'm not entirely clear on how to choose a Twine version.) What are the important considerations? When does it make sense to choose one over another?
I had initially assumed they were just style sheets, but it's becoming increasingly clear to me that they are something more akin to mutually incompatible programming languages with different capabilities.
