Sorry for the incredibly embarrasing newb question, but this has been bugging me for a while and I can't go on until I get it right.
As a GM, I don't know how risks work exactly. I understand the basic rules to resolve a risk, and then we have an action sequence (or Action Scene), which is a series of risks/rolls/rounds. This emulates action rounds in more traditional RPG's.
But then the rulebook introduces Dramatic Sequences or Dramatic Scenes.... extended scenes which are resolved through only a single roll. And here I get confused. Why not treat it as a series of rolled challenges?
Let's say we have a hero who wants to infiltrate a villain's mansion. We treat it as a Dramatic Scene, determine approach and narrate through it all until the hero runs out of raises. But why not treat this as a series of risks/die rolls?
What am I reading wrong? How are you using Dramatic Scenes?
