Single Button, Handheld Gaming Console

Those of us who grew up in the 70s and 80s might be familiar with the Atari 2600 console and its now relatively unrecognizable (by modern standards) controller with only a single button and stiff whole-hand joystick. By comparison, the Steam Deck has somewhere around 24 buttons and two joysticks depending on how they are counted. But even the Atari might be providing more user inputs than are really necessary for quality gaming.
