As always when I read Kevin Crawford's stuff, firstly it just makes me want to game, then fervently wish he would someday write a novel set in his Stars Without Numbers/Other Dust universe. This isn't your standard tech manual, some of the devices presented herein are pretty esoteric, science sufficiently advanced resembling magic and so on, but the signature of his products are the well organised generation tables to enable time-poor GM's to quickly generate material for their home campaigns. SWN has broad setting outlines set upon a simple ('basic system' or Labyrinth Lord) rules, the rest is an endless sandbox- this supplement focusing on locales and devices of 'lost' civilizations. Another triumph for Sine Nomine!
