Recently, I went back and played most of the Rare games, mostly for the N64.
And man, they aged really really terribly. I thought they were cool when they came out, but by today's standards they're just awful.
Goldeneye being the worst, others like Donkey Kong 64, Diddy Kong Racing, etc.
The only exceptions are Banjo Kazooie and Conker's Bad Fur Day.
