Zork is the quintessential text game. There's no need to click your mouse, maneuver a joystick or mash a d-pad. All you need is the ability to read, type and think somewhat logically. The amusingly clever text adventure was developed on a PDP-10 mainframe at MIT in the late 1970s.
Three of the four original programmers went on to found Infocom, which released the Zork Trilogy for many popular microcomputers in the early 1980s. Three decades later, you can play it on your web enabled fridge for free. That's true progress.
