Im a big fan of SJ, super happy that its beenn officially released for 5e. This book adds a much needed layer of clarity and depth that the Astral Adventurer's guide lacks. Namely it has expanded ship combat rules, ship repair rules (actually fixes it) and best of all, specific roles for crew actions that make Wildspace combat really fun. This supplemant also gives you a separate file for crew roles that you can easily print and hand to players. Overall, this is probably the best fan produced expansion for SJ 5e yet. Highly recommend it if you want a more detailed and better balanced ship combat rules system while keeping the 5e design philosophy of keepinng rules simple.
