A video game (VG) is an electronic game that involves human interaction with a user interface to generate visual feedback on a video device. The word video in video game traditionally referred to a cathode ray tube (CRT) display device, but it now implies any type of display device that can produce two or three dimensional images. The electronic systems used to play video games are known as platforms; examples of these are personal computers and video game consoles. These platforms range from large mainframe computers to small handheld devices. Specialized video games such as arcade games, while previously common, have gradually declined in use. Video games have gone on to become an art form and industry.
The input device used to manipulate video games is called a game controller, and varies across platforms. For example, a controller might consist of only a button and a joystick, while another may feature a dozen buttons and one or more joysticks. Early personal computer games often needed a keyboard for gameplay, or more commonly, required the user to buy a separate joystick with at least one button. Many modern computer games allow or require the player to use a keyboard and a mouse simultaneously. A few of the most common game controllers are gamepads, mouses, keyboards, and joysticks.
Akihabara (Japanese: 秋葉原?) "Field of Autumn Leaves", also known as Akihabara Electric Town (Japanese: 秋葉原電気街, Hepburn: Akihabara Denki Gai?), is a district of Tokyo, Japan. It is located less than five minutes by rail from Tokyo Station. Its name is frequently shortened to Akiba (アキバ?) in Japan. While there is an official locality named Akibahara, which is also 秋葉原 in kanji, nearby (as part of Taitō-ku), the area known to most people as Akihabara (including the railway station of the same name) also include Soto-Kanda, a part of Chiyoda-ku.
