Just wondering, what games are there out there which only use buttons ... no joysticks or other controllers.
What comes to my mind are Asteroids and Asteroids Deluxe, Astro Blaster, and Phoenix ... but are there others that just aren't coming to my mind?
What about games that had more than one configuration? (I know I saw Phoenix machines that had a joystick and two buttons, rather than four buttons.)
Just wondering how many games I am missing.
