This game is revolutionary, and Dune 2 is widely regarded as the first real time strategy game.
It involves principles of resource management. A player has to farm spice, and using this spice can purchase soldiers and military buildings that can be used to produce war machines.

While this is happening, a computer opponent also mines spice, creating soldiers and war machines. The computer opponent will try to destroy all your mining equipment, soldiers and war machines, and you have defeat the computer before the computer defeats you.
A game truly before its time, but was still successful.
