There’s videogame history, contemporary touchstones like Half-Life, Doom, Civilization, and Zelda, and videogame history. Before the visuals, mechanics, and rounded tropes of today’s established genres were fully realized, early pioneers – visionary software programmers and computer scientists – built the foundations by hand. Through Stellaris, Total War, and XCOM, strategy games remain one of the cornerstones of the PC as a platform. But their history goes back much further than you might think. Lost to the ether for 60 years, The Sumerian Game, one of the genre’s earliest cave paintings, is back, rebuilt, and available for free on Steam.
