The legendary planet Dune did for RT strategy, what Wolfemstein 3D did for first-person shooters. At almost fifteen years old, this is the mother of all strategy games. Your mission is to build a functional base using the facilities on offer, and to construct a powerful army that will face and defeat opposing forces. You may choose from four houses, much as you could pick GDI or NOD in the Command and Conquer series.

Dune II was a defining game which has influenced countless others since then. Anyone that wants to see raw gameplay at its best from the early 90s, download this.
