I started with an action opening, so like a semi-full score, but it went well. Then we did downtime and next plot hooks. Honestly, I see why you could find it stressful, it relies on improvising a lot, but it's also somehow less stressful for me compared to knowing I have prep work to do before my d&d game. I can actually see myself running two campaigns if one is Blades and other is something more prep-heavy like d&d. I'll if I have the same opinion after few more sessions. I hope I do.
