Huge game :) As a Breathless designer myself, I want to share my love for this book. Recently played an “alienating time paradox” hard sci-fi scenario with a single player and we had a blast with all the table inputs. :)
I always expand a bit on the Role utility and such, but in general, this game works wonders to show the genre. :)
I might advice, for any future revamps, that Role might grant more than a d12, like customisable stunt actions (I did a similar thing in my Breathless Dungeons game, you can check out the preview to see what I mean, if interested :) )
I might polish and post my above mentioned Cargo scenario someday soon :)
