First off, I think this thread will be informative for the question you’re asking.
There’s also some very good discussion about BitD Actions vs. PbtA Moves in this Twitter thread:
One thing I like about that second thread in particular is that John Harper described BitD Actions as a custom move-generation system. Instead of “Turn Someone On” or whatever (which is a fairly specific move), you could have a Desperate Prowl with potential Great Effect, modified by Push Yourself and an Assist from a teammate.
To me, the customization potential around the Action/Position/Effect/Modifier conversation is a key design pillar of Blades. But as John says in the first thread: beware simple categorizations… they’re always wrong! I know of a few hacks that make fairly big departures from that Action/Position/Effect/Modifier conversation.
