That control panel is too narrow, and those sticks are too close together, for comfortably playing two player games—unless both players are about 12 years old or less. It looks like it would work good for Robotron though, or even single-player Karate Champ.
And why do they have a "Non-Functional Display" out there? Who would buy something like that without seeing what the picture & sound quality, accuracy of play, control responsiveness, etc., are like?
