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.)
Lol that’s pretty funny. I highly recommend revisiting it! Also, soooo many amazing games in that franchise. You gotta check at least a few of them out!
