I've always imagined the ornithropters being these airplane-like vehicles with wings that beat really fast, sort of like a housefly's wings. Is that how they're done in the games?
The House colors were REVERSED?! Now THAT I didn't expect! I guess it was influence from the movie that made me think otherwise.
But overall, the thing I love most about the Dune saga is that it seems so REAL; I mean, if man really did travel out into space, inhabiting different planets all over the galaxy like in the saga, I think we really would be a lot like Frank Herbert portrayed us. New cultures would develop, man would try to rule it all in a single government with planetary "houses," some people might see machines as evil, especially if they believe the machines will become self-aware, there would be new subspecies of humans, and any kind of space-folding technology would probably be kept in monopoly by a single organization similar to the Spacing Guild to keep it out of the wrong hands. I can bet a trillion dollars that in the distant future, Frank Herbert will be seen as a sort of modern Nostrodamus!
