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.)
Skyrim. It’s a beautiful game, even now when I play it I take a moment to just look at how gorgeous the scenery is. I love the quests and that you can own a horse/house/child/ get married. I love the potions and crafting and customisation.
I don’t think there are many games quite like Skyrim
