Super Mario Galaxy was my first console game, got it for Christmas the year it was released. I went from Super Mario Bros. Deluxe to this huge 3D adventure across all these creative and beautiful environments, of course it blew my little kid mind. I would spend so much time in Beach Bowl Galaxy swimming with the penguins and swinging on that vine. The music is the best Mario has ever known. Not a single level in this game makes me groan when having to go back to it on a new run. The Comet Observatory feels like home.
