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.)
I’m guessing that’s down to it having a wider appeal than the average Roguelike. A lot of folks will have played it for the plot, which can be neatly wrapped up in around the first 20 hours. There’s still plenty to do after that point, though.
