Following something, building on something or transcending something is not the same - obviously. But both use “the something” as an inspiration, right?
For a lot of people, including myself, AW as a whole RAW set an example in analog game design which is worthwhile to follow.
But for Vincent, it was just the formulation of his know-how back then. Since that he diverged very far (maybe the furthest?) from PbtA as AW. Just check his Patreon stuff! Some genes (memes?) from AW are still there, but these are completely different animals.
Of course, a lot of smart designers are “in the middle” so to speak with nuanced, deeper hacks.
