Command & Conquer

From Wikipedia

Command & Conquer, abbreviated to C&C and also known as "Tiberian Dawn", is a 1995 real-time strategy computer game developed by Westwood Studios for MS-DOS and published by Virgin Interactive. It was the first of twelve games to date to be released under the Command & Conquer label, including a prequel and five sequels. On August 31, 2007, current publisher and owner of the C&C franchise Electronic Arts made Command & Conquer (Windows95/Gold version) freely available for download from their official website, to mark the franchise's 12th anniversary.

Set in an alternate history 1995, Command & Conquer tells the story of two globalized factions: the Global Defense Initiative of the United Nations, and the ancient quasi-cult, quasi-state organization, the Brotherhood of Nod. The factions become locked in a mortal struggle for control over a mysterious resource known as Tiberium that is slowly spreading and infecting the world.

Met with acclaim by consumers and critics, Command & Conquer was released for seven separate platforms along with becoming the initiator of the Command & Conquer franchise, and today generally is considered as the title which originally defined and popularized the modern real-time strategy genre.
