exclusives

Platform exclusivity (also known as console exclusivity) refers to the status of a video game being developed for and released only on certain platforms. Most commonly, it refers to only being released on a specific video game console or through a specific vendor's platforms—either permanently, or for a definite period of time.
Exclusivity is a topic used in discussions of the advantages and disadvantages of rival vendors in the video game market, and one which is used for marketing by vendors involved. Industry analysts generally agree that there is a correlation between availability of exclusive titles, and hardware sales.
