The greatest supplement for Stars Without Number to date. It has everything from how to build a navy for a planet, to fullscale naval conflict resolution. It only lacks one thing, the inclusion of the Psychic character class, I was thinking of seeing a Psychic Astrogator, or a Psychic Gunners Mate, especially after see the Precognitive Nav Chamber, in the Core Book, or at least some further rules for usage of the device. But alas, the MESses are left out in the cold again. But other than this small criticism, there are no equals to this game. I have been overjoyed with from my first purchase of the core rulebook. Keep up the good work, and please add some love for the Psychic.
