For example, the Dune in the movie shows no natural vegetation whatsoever, which is not the case for our Dune. The game requires us to go further yet and adopt a more global view of the planet.
The movie is of course a strong visual reference for many iconic aspects of the universe, like the Ornithopter or the sandworm. Having said that, we draw from everything, including the most recent movie by Villeneuve, and even various real-life locations like the Oregon Dunes, the southern deserts of the USA, Wadi Rum, the Acacus Mountains, Tassili n’Ajjer, Ennedi, and even planet Mars. Our main source is the books, principally the ones written by Frank Herbert. Dune is a universe so rich that we’re spoilt for sources of inspiration.
