Battlezone (1980)

Atari's Battlezone at the Musée Mécanique in San Francisco, in the upright with a shroud around the screen, so you lean in and look at the battlefield through a viewer. The 1980 game draws wireframe tanks on a vector display under a green and red overlay. Below sit two joysticks that each move only forward and back, one of them carrying the fire button. Steering by pushing the sticks against each other takes a minute to learn, and then it feels like driving a tank.
