This game has aged very well. You can pick it up for next to nothing on GOG. Highly recommended. The game is not very hard but you will likely have to start over a few times before you get the hang of it. This is normal. Dune is best without spoilers, so maybe skip the video.
There are some rights issues that prevent them from coming out anywhere if I remember correctly. One of those deadlocked cases it seems. And involved parties didn't care about working things out.
