Nice work! I have some questions:
1. Did you mention how assigning results with multiple threats works?
2. At multiple occasions you do mention how help from another crew member boils down to them spending 1 stress as requirement - isn't that the old way?
3. You talk about spending 2 stress to improve your roll - isn't that the old push mechanic?
4. Shouldn't struggling because of your ambitions be mentioned as XP trigger?
