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.)
Fata Morgana.
Listen, whether you like Visual Novels or not doesn’t matter. But Fata Morgana is just somehow…perfect. Everything is resolved and I don’t feel any need to complain about any aspect of it. It was an experience to play a game that left me with no questions afterwards. It was just a really good story.
