Diaspora is a "Hard" Sci-fi role-playing game based on the FATE engine from Evil Hat Productions.
History
VSCA Publishing in Canada released the first edition of the science-fiction game, Diaspora in 2009. The game used the third-edition of FATE. Diaspora was one of the FATE games to include a method to collaboratively create a campaign among the players, and gave extensive rules for collaborative creation of worlds in space. Fred Hicks noted that Diaspora was one of his favorites, and got it into wider distribution by reprinting it through Evil Hat Productions in 2010.
