Steamscapes Asia is a Savage Worlds licenced product, the second in the Steamscapes steampunk setting. Both products are source books only so you’ll need the Savage Worlds. If you’re looking for steampunk mechanics for Savage Worlds, you’ll only need a third of the book. But that’s not the intent of the book. The intent of the book is to enjoy yourself reading an alternate history textbook and tour guide complete with in setting fictional primary sources. In this it succeeds.
