Mixed narrativist-gamist. no significant concessions to simulation. It's roughly comparable to Firefly on that score: both are more naarativist than gameist, but very much not fully either. It's a touch higher on compleity than Firefly, and about equal to MHRP.Having run SCRPG, while I am sure that a person steeped in GNS theory would be able to analyze it, I don't think it was created from a very GNS-centered point of view. It is a post-GNS game, so GNS is perhaps not the best tool to figure out how to run the thing..
