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.)
Super Mario RPG for SNES. … I’m old
Easily one of my favorite RPGs.
Also it’s getting a remaster(and I’m not old :P) so there are and/or will be more young fans than what you realize
