Halo...

Now that I'm cool too, let's go for my real answer: Starfox Adventures. I imagine the logic behind it went something like this:

Johnson: "Let's make a new Starfox game, but instead of a cool space shooter, make it a platformer. Not only that, but we can make one button do everything, but only let you use moves when we tell you, and throw in some fetch quests. Everyone loves fetch quests. While we're at it, we can make Fox's friends even more annoying. Heck, forget the game, let's just give the player a free bag of vomit to just pour on their Gamecube."

Rare president: "Why not? We've already ruined Donkey Kong."
