If you're into anything real-time strategy-like, especially Command and Conquer, then this is the father of them all. Developed by Westwood Studios in 1992, Dune 2 (as created by Frank Herbert in his novel of the same name, which was later turned into a film starring Sting out of The Police), gave the player a series of real-time battles to play through in one of three houses: Ordos, Atreidies and Harrkonen. Essentially, the idea was to gather Spice and turn the profits into hardware for your war machine. Then you went and kicked the other houses' arses. The 'tank rush' was born.

Dune 2 wasn't as polished as today's RTSes and suffered from a couple of gameplay bugs (you could get the computer players to destroy their own installations if you positioned your units carefully) but it was immensely absorbing and allowed several strategies to be employed to achieve the game's objectives. A genre was born and Dune 2 went on to be converted to the PC, where it achieved similar success. Its successor, Command and Conquer, appeared a couple of years later and that's a game that needs no introduction. Dune2, we salute you.
