Earth 2140 is an old-school RTS in the vein of Command and Conquer. Strangely, it had more of a following in Turkey than in American and Europe. It told the story of two warring factions: The Eurasian Dynasty and the United Civilized States. This is your typical dystopian future, where Earth has been bombed into a nuclear wasteland and rival factions are at war for the world’s remaining resources. This is pure 4X strategy gameplay (expand, exploit, explore, and exterminate). Gather resources, build bases, and construct units. The soundtrack is a strange blend of jazz and adult contemporary, and the plot is light compared to the sequels. However, this is still a fun classic RTS. You can buy it from GOG.com for $5.99, and teh game includes the DOS version, and both expansion packs.
