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.)
Holy shit Chrono Trigger rocked my world so fucking hard. I played it on an emulator in like 2000. I’ve forgotten a lot of stuff yet I still remember the impression this game left on me. It was like holding my breath at the end there goddamn.
