My local group has finished playing several sessions of S7S, and we enjoyed it a lot. Our prior game of Diaspora had fallen kind of flat, so it has been nice to simply embrace a genre and run with its tropes. No unique snowflakes or weird character types, just your typical roguish privateers from various nations who keep their word to paying passengers despite the obstacles along the way.
Mechanically, the game worked for me pretty well, though there are some things I’d do differently in character creation next time around. Peter, our GM for the game, started a thread at Story Games about our game, so I’ll simply point there rather than repeat our observations.
