I've never seen a GM-less system before. Is there anywhere I could watch a session of this or something similar so I can get the vibe of how it works? I'm also down to join a group for playtesting if anyone's looking.
Totally get that, it took me a while to wrap my brain around GM-less! I’m planning to record a play-through of Space Bounty Blues this week, but in the meantime you could check out this series on GM-less games: https://gameswithoutmaster.blogspot.com/
Fiasco is probably the best one to watch played—it somewhat fits SBB tonally and structurally, and there are some really entertaining sessions on YouTube!
