A computer or video game uses one or more input devices

Video games are computer- or microprocessor-controlled games. Computers can create virtual spaces for a wide variety of game types. Some video games simulate conventional game objects like cards or dice, while others can simulate environs either grounded in reality or fantastical in design, each with its own set of rules or goals.

A computer or video game uses one or more input devices, typically a button/joystick combination (on arcade games); a keyboard, mouse or trackball (computer games); or a controller or a motion sensitive tool (console games). More esoteric devices such as paddle controllers have also been used for input.

In more open-ended computer simulations, also known as sandbox-style games, the game provides a virtual environment in which the player may be free to do whatever they like within the confines of this universe. Sometimes, there is a lack of goals or opposition, which has stirred some debate on whether these should be considered “games” or “toys”. (Crawford specifically mentions Will Wright’s SimCity as an example of a toy.)
