Well, Zelda's a huge franchise that has historically been the killer app for every new Nintendo platform!

Psychonauts was criticized for its somewhat flat platforming and repetitive gameplay scenarios but praised for its unique design, original story and wild creativity. Also, by the time it was released, Platforming was on its way out. it was the big thing when they were developing it, but the genre sort of ran out of gasoline by the time it was released.

BG&E is all around genius with fun and diverse gameplay and a great story. I think BG&E borrowed heavily from Zelda, even though it didn't have the puzzle depth that Zelda has. I'm surprised with Ubisoft's good name and PR machine that BG&E wasn't better received in the public.

Both were marketed poorly, especially Psychonauts. Definitely get it on steam like Achim says, or gamesload.

But then again, mediocrity can be pretty popular. Brainless Hollywood movies are far more successful than less hyped independent or small studio films, McDonalds and The Olive Garden outsell smaller better quality restaurants, etc etc.

Not that Zelda is the McDonalds of videogames!
