StarCraft is a real-time strategy (RTS) game developed by Blizzard Entertainment. It was first released for Windows in March 1998, and later ported to Mac and the Nintendo 64. Set in a science-fiction universe, the game lets you command one of three factions: the human Terran, the insectoid Zerg, and the advanced Protoss.
Unlike turn-based strategy games, everything in StarCraft happens in real time. You gather resources (minerals and vespene gas), build bases and armies, and fight your opponent on a single map. The balance between the three races, the depth of unit and tech choices, and the skill ceiling made it incredibly popular for both casual play and competitive matches.
StarCraft became a phenomenon in South Korea, where it was broadcast on TV and played in professional leagues. That scene helped turn video games into a spectator sport and influenced how we think about esports today. The expansion Brood War (1998) added more units, campaigns, and maps, and many players still consider it the definitive version of the game.
If you enjoy classic PC strategy or want to see where modern RTS and esports got their start, StarCraft is well worth playing—or watching—today.
