Multiple Players (Ambidextrous)
Multiple Players (Ambidextrous) is part of the category Control Panel Layout.
Games which allowed more than one player at a time and featured featured a control panel layout with secondary controls (such as buttons) mirrored on both sides of the primary controller (such as a joystick). This allowed both left handed and right handed players to play the game using controls they found more comfortable.
