i got into Dune via the games. I just thought the plotline was more interesting than others. Then i found out there were books about it. So i went out and read the original dune book. Must say that I loved it and i went on to read the preludes i.e. the Houses of Atreides, Harkonnen and Corrino. Those three books were just like set prior to the actual Dune novel. Then I found out there were more preludes such as the Butlerian Jihad, Machine Crusade and The Battle of Corrino. It tied so much up in the history sense because the books just manage to fit in so well. I find it kinda funny since so much stuff is happening round Dune and yet the planet itself never changes. The sand, spice and worms are still there. I haven't had time to go and find the novels set after Dune.
