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.)
Hollow knight. The gameplay, the smoothness of the controls, but also the universe, the atmosphere, the fantastic music. Absolutely wonderful game.
Hollow Knight is the best game I’ve inexplicably never finished
