Dune 2 = video game = arguably the originator of the RTS series. Made by Westwood Studios waaaaaaay back in the day.
You had House Atreides, House Harkonnen, and House Ordos.
Harkonnen believed in superior firepower, and generally had the guys with the biggest guns. And their special weapon was a nuke! Although the special weapon of the Atreides was the Freman, which was pretty nice because they were autonomous Heavy Infantry (which were pretty powerful, had strong guns and a rocket pack as well) squads that would go around wreaking havoc until they were destroyed.
It was good fun!
