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.)
Control seems pretty good at what it wants to do. Nice graphics and soundtrack, fluid movement in combat (closest description I could think of) and cool, intriguing story. It also has one of the best video game quests I’ve played: Ashtray Maze
Skyrim (despite the numerous bugs) is another one I will say is close to perfect. Really good game and the community is pretty great as well.
