Super Mario Galaxy is a complete masterpiece in virtually every way and is in my opinion the best 3D Mario game to date. The level design is immaculate and the atmosphere is unmatched, and that's not even mentioning the outstanding soundtrack. To this day, Rosalina's storybook is the most impactful and meaningful piece of Mario storytelling ever put into any of the games. I could go on and on, but I'm sure most of you out there already know how good this game is.
