I believe The Beatles: Rock Band came the closest to being perfect. Eveything about that game was just beautifully done and the only things missing was Pro Drums, an option for Keys, and a few more Beatle songs (Hey Jude, Strawberry Fields Forever, Yesterday etc. etc.)
Zelda Links Awakening. It’s a perfect clock, every wheel in place.
I’m more into links awakening, but they are really the same era and similar in many ways.
