Video game accessory
A video game accessory is a distinct piece of hardware that is required to use a video game console, or one that enriches the video game's play experience. Essentially, video game accessories are everything except the console itself, such as controllers, memory, power adapters, and audio/visual cables. Most video game consoles come with the accessories required to play games out of the box: one A/V cable, one AC cable, and a controller. Memory is usually the most required accessory outside of these, as game data cannot be saved to compact discs. The companies that manufacture video game consoles also make these accessories for replacement purposes as well as improving the overall experience. There is an entire industry of companies that create accessories for consoles as well, called third-party companies. The prices are often lower than those made by the maker of the console. This is usually achieved by avoiding licensing or using cheaper materials. Wikipedia
