Dinosaur Planet was an unreleased game for the N64 which later was pushed to the Gamecube, and remade into the Starfox universe as Starfox Adventures. While the N64 version lacked Fox McCloud it did show some promise.
It seemed to be Rare's answer to Zelda just as Banjo-Kazooie was their response to Super Mario 64.
Krystal was even a playable character, and no that intro to Adventures doesn't count.
While I rode the hype train for both Dinosaur Planet and the eventual Starfox Adventures, I was extremely disappointed with the final game. But it's still neat to see it's origin.
