Q-Bert (1984)

One of the few popular educational titles. It provided perfect training for life: you spend all your time doing and undoing pointless things simply because someone told you to, one wrong step and you'll ruin everything, and other people will devote themselves to undoing even your thankless task for no other reason than they can.
