A video game is an electronic game that requires interaction with a user interface or input device such as a joystick, controller, keyboard, or motion sensor to generate visual feedback on a two- or three-dimensional video screen like a television, monitor, touchscreen, or virtual reality headset. Video games are complemented by audio feedback through speakers or headphones and optionally with other types of feedback systems, including haptic technology. Video games are categorized by their platform, such as arcade games, console games, and PC games. Recently, the industry has expanded to include mobile games on smartphones and tablet computers, virtual and augmented reality systems, and remote cloud gaming. Video games are divided into a variety of genres based on the type of game and its purpose.
