The games vary greatly in type and complexity, but all games are alike in that they translate player input (from a controller, mouse, keyboard or motion sensor) into onscreen actions. Games are usually stored on some sort of digital media - ROM cartridge, [[CD]], [[DVD]], or even cassette tape for early computer games - though older or more inexpensive games may have dedicated chips which are pre-programmed to play certain games only. In recent years, game developers have moved to digital distribution, allowing anyone with a credit card or [[Paypal]] account to purchase games online.
