My group played through this game over a couple of sessions (could easily have gone longer). It was an absolute blast! Our first foray into GMless games. Never had to wonder what to do. There's always something interesting happening for you to interact with.
It does take a VERY different mindset to play than D&D. So be aware of that if you come from D&D or similar games. But give it a chance and I'm sure your group will love it!
Also, I'm now using Starflung Missives from the bonus material for a letter writing game with my penpal. Lots of fun!
