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.)
Final Fantasy 6 and Monkey Island 2. I’ve replayed both many times and each is perfect all the way through.
I rarely see point and click adventures on lists like this, maybe because their popularity dropped like a rock and never recovered, but MI2 deserves a play through for anyone who hasn’t played it.
