The situation still has primacy in a way it does not when it's derived from a fixed setting. Because the situation is constrained intrinsically by the setting, you can use those fixed points to reframe a different situation before you start spending resources to resolve it.
Things get "nailed down" in the course of play (prior play and current play) such that situation is constrained intrinsically by the setting all the time in BitD. Players develop multiple lines of play to reframe situation routinely. Last game for example:
* The assassination target was having an affair. The players had his love letters as (high Magnitude) Documents that could be used to inflame his wife to do the killing.
* His armored carriage was due for maintenance and the Crew is +3 Faction with the Cabbies and Duskvol garage. This could be used to affix a high Magnitude bomb w/ timer to either kill the target outright if you could get him out of his fortified estate or perhaps smuggle said massive Magnitude bomb to blow up the rear of the home for calamity, security personnel devastation, and ingress (while covering or assaulting the front).
* The exterior, load-bearing, masonry wall had an ancient dumbwaiter shaft, accessible via the undercity canals, that was long ago bricked over. This could be accessed via jaunt through the (dangerous) undercity canals, demoed, climbed, quietly demoed attic framing for ingress, assassinate via Master Suite plaster and lathe ceiling, egress. Or use it to affix a high Magnitude bomb with a timer in the attic-space.
* The manor is the NW quadrant of Brightstone with the Bowmore Bridge leading over to Whitecrown Island (where his lover is). Could wait out the next scheduled rendezvous, or force one via assaulting the manor's front (creating the target's egress via armored carriage through the back), and either assault on the bridge or plant the massive Magnitude bomb on the bridge and BOOM.
All of these were either established via prior fiction/Score(s) or Info Gathering. Blades is a game whereby you are constantly building out setting outright (procedurally or establishing what is provisional) or building out setting via situation and the resolution of situation, which in turn establishes new lines of play/situations, which in turn establishes new setting (rinse and repeat).
