A video game is an electronic game that involves interaction with a user interface to generate visual feedback on a video device. The word video in video game traditionally referred to a raster display on a device. However, with the popular use of the term "video game", it now implies any type of display device. The electronic systems used to play video games are known as platforms; examples of these are video game consoles, personal computers, and mobile devices. Specialized video games such as arcade games, while previously common, have gradually declined in use.
