I love blades. I love love love blades.
What I like to do is to postpone crew creation until after the first score. Front load that heist goodness. The main trouble with getting players in the blades mindset is getting them to skip preparation. They can’t prepare if you literally start the game with them hanging on the outside of a building or on top of a moving train.
I also work hard at first to get the players to contribute to the story. Having them come up with devil’s bargains for each other is always a good start. Eventually they’ll start taking more initiative.
For scores, I deliberate under-prepare. I always have a bunch of possible scores prepared, but they are just index cards with a single sentence summary on them and then three (3) obstacles. That’s it. It’s up to the players to figure out how to get it done.
