Rare Limited is a British video game developer and a studio of Xbox Game Studios based in Twycross, Leicestershire. Rare's games span the platform, first-person shooter, action-adventure, fighting, and racing genres. Its most popular games include the Battletoads, Donkey Kong, and Banjo-Kazooie series, as well as games like Killer Instinct (1994), GoldenEye 007 (1997), Perfect Dark (2000), Viva Piñata (2006), and Sea of Thieves (2018). Tim and Chris Stamper, who also founded Ultimate Play the Game, established Rare in 1985. During its early years, Rare was backed by an unlimited budget from Nintendo, primarily concentrated on Nintendo Entertainment System (NES) games. During this time, Rare created successful games such as Wizards & Warriors (1987), R.C. Pro-Am (1988), and Battletoads (1991). Rare became a prominent second-party developer for Nintendo, which came to own a large minority stake in the company, with the release of Donkey Kong Country (1994). Throughout the 1990s, Rare started selling their games under the trademark name "Rareware" and received international recognition and critical acclaim for games such as the Donkey Kong series, Killer Instinct (1994), GoldenEye 007, Banjo-Kazooie (1998), Perfect Dark, and Conker's Bad Fur Day (2001). In 2002, Microsoft acquired Rare, which retained its original brand, logo, and most intellectual properties. Rare has since focused on developing games exclusively for Microsoft's video game consoles, including Grabbed by the Ghoulies (2003), Kameo (2005), Perfect Dark Zero (2005), and Viva Piñata (2006). In 2007, the Stampers left Rare to pursue other opportunities and, in 2010, the company's focus shifted to the Xbox Live Avatar and Kinect, releasing three Kinect Sports games. In 2015, Rare developed Rare Replay, an Xbox One-exclusive compilation containing 30 of its games to celebrate its 30th anniversary. Rare's most recent game, Sea of Thieves, was released in 2018. Several former Rare employees have formed their own companies, such as Free Radical Design, best known for producing the TimeSplitters series, and Playtonic Games, best known for Yooka-Laylee (2017). Rare is widely acknowledged by the gaming industry and has received numerous accolades from critics and journalists. It is known as secretive and seclusive. Several Rare games, such as Donkey Kong Country and GoldenEye 007, have been cited as among the greatest and most influential games of all time, though some fans and former employees have been critical of the company's output since the Microsoft buyout.
