Other Dust is an excellent companion to Stars Without Number, and a wonderful modern example of sandbox gaming. Other Dust uses a slightly updated version of the classic AD&D 'engine', adapted for sci-fi gaming. The setting seems a bit grimmer and more serious than older post-apoc RPGs like Gamma World, which is a clear inspiration. That feeling of realism comes from an amazing setting conceit, one I wish I'd thought of first. Instead of radiation causing mutations, a malfunctioning global emergency system, called the HighShine, unleashes out of control healing nano-colonies upon those suffering from radiation poisoning or other trauma. To modern gamers, this might be more plausible than the old 'radiation as magic' tropes.
Aside from the brilliant HighShine concept, the real greatness of the sourcebook is found towards the back. A phenomenally deep random creation system will allow you to build settlements, plot out adventures, dress sets ranging from a limestone cavern to an abandoned factory in seconds.
I'd been waiting to write this review until my print copy of the book arrived. Fortunately, Other Dust looks as good in print as it does on screen.
