Oh wow, that takes me back.. This game actually got me into reading the book. I played so much of this when I was little, I loved the story and the characters.
When I saw the movie in the rental store I got really excited. I didn't even know there was more to Dune than the game. I asked my parents if we could rent it but my dad told me (rather gruffly) to go and read the book instead.
I was so annoyed at the time, but looking back I have to admit he did the right thing :)
