They are all great companies/games but in Rare's prime they were knocking out 4/5 titles a year and they were mostly all great games.
Blast Corps, Goldeneye, Diddy Kong Racing in '97
Banjo-Kazooie in '98
Jet Force Gemini, Donkey Kong 64 in '99
Perfect Dark, Mickey's Speedway USA (I didn't even realise this was Rare until now good game), Banjo-Tooie in 2000
