Zork (1980)
As it became more common for the average home to have a personal computer, video games were an obvious addition to the software library. Originally created by MIT developers, the text-based game used the PC’s then lack of graphic interface as a virtue, creating an interactive adventure that was entirely visualized in the players’ minds. Without it, there would be no “Venture,” “Zelda,” “Final Fantasy,” “Dragon Age” or “Skyrim.”
