Frank Herbert's Dune CYOA

From the introduction: This saga is not one of glory and freedom for the Fremen, nor how their Jihad will bring all humanity to the true Zensunni Path. Their destiny is linked to the destiny of all mankind. For too long has humanity lain stagnant, trapped in the rigid class structure and imperial peace of the Padishah Empire, which controls the entire Known Universe through CHOAM, the single megacorporation that all noble families are part of.
