This game was released in 1993 and by the same people who brought us Command & Conquer 2 years later.
So in this game you take control of 1 of 3 families and fight for control of the planet Arrakis in a short campaign. Each house has some unique units and powers. It's very much like command and conquer.
If you liked Command & Conquer it could be worth checking out. They had a version for the PC as well.
