Rare

Rare (formerly known as Rareware) is a developer based in Twycross, England. Although they were popular in the early 80s as Ultimate (or Ultimate Play the Game), their true claim to fame was the massively popular Donkey Kong Country series. They are also often credited for being largely responsible for the Nintendo 64's success, by being a Second party to Nintendo, and developing N64 classics like Banjo-Kazooie, GoldenEye 007 and Jet Force Gemini. In late 2002, the Stamper Brothers sold their shares of Rare to Microsoft, which then prompted Nintendo to do the same.

Since being bought by Microsoft, Rare has developed a few games for Xbox 360, among those games are: Kameo: Elements of Power, Viva Piñata, Perfect Dark Zero and their latest release Banjo-Kazooie: Nuts & Bolts.
