I love John Harper's Blades in the Dark, and some friends and I are going to be running some one-shot games at an upcoming convention.
But, a lot of the things that make Blades so cool is how nicely it ties in long-term consequences and developments. You can start long-term projects; you have ongoing relationships with different factions; you have complications and entanglements from earlier events catching up with you now...
Even the most basic mechanic, Stress, isn't a big deal if you start out with zero Stress, and aren't likely to reach Trauma in the space of a single session.
I'm fine with having loose ends, or doing a "Previously on Blades!" schtick where I fill in some imaginary backstory and some existing complications.
Are there any adjustments that I should make, in order to give the full "feel" of the game, and its panache for long-term consequences, in the space of a single session?
