Video game
A video game is typically user controlled, interactive software that generates visual feedback on a monitor based on a user's input, that is played for entertainment. Various different types of games exist, some where two or more people can also play, either cooperating, or in competition with each other.
Platforms
Video games can appear on many different platforms including console video games, computer video games, arcade video games, and hand held devices including hand held gaming systems, PDAs, and cellular phones.
Video games are typically manipulated via an input device. This input device varies from platform to platform but may include a joystick, a mouse, a keyboard, pedals, a phone number pad, or a console specific controller. Video game controllers have evolved over the years, and now some even simulate movement, such as when fishing or bowling.
